    MAGNETIC STORM IGNORES FORECAST: Ignoring Spaceweather.com's forecast of a quiet weekend, a G1-class geomagnetic storm erupted during the early hours of May 21st.  The brief disturbance occurred around 09:00 UT when Earth passed through a region of interplanetary space filled with negative polarity magnetic fields.  Such fields open a crack in Earth's magnetosphere, allowing solar wind to pour in and fuel storms.


    MIDNIGHT SKY SHOW: Tonight, around midnight, step outside and look south. The full Moon is passing by Mars and Saturn, forming a luminous triangle in the constellation Scorpius. You won't need a sky map to find them, but just in case:
    The Moon and planets are easy to see with the naked eye. Pay special attention to the intense rusty-red color of Mars and subtle golden hue of Saturn. The contrast is beautiful.


    If you have a telescope, take a closer look. The rings of Saturn are easy to see through backyard optics. Ditto for the ruddy disk of Mars. The Red Planet is just finishing winter in its southern hemisphere, so be alert for a bright polar cap at the martian south pole. 


    This meeting in Scorpius occurs just 8 days before Mars makes its closest approach to Earth in a decade. Note the location of Mars tonight so you'll know where to look again on May 30th--the Night of the Red Planet!

    Stargazers to get rare glimpse of Blue Moon, bright Mars this weekend
    There will be a Blue Moon Saturday night

    Mars will become one of the brightest bodies in the sky starting Sunday


    Cloud cover may hamper the experience for South Florida stargazers

    There is an astronomical phenomenon known as a Blue Moon which happens, you guessed it, only occasionally. And it’s happening this weekend.

    In fact, Saturday and Sunday will offer a dual opportunity for stargazers to get excited because aside from the infrequent Blue Moon Saturday evening there will also be some high-jinks from Mars on Sunday evening.

    Mars will be in opposition, meaning the Earth will be passing directly between Mars and the sun. That could make Mars brighter than any star or planet in the night sky.
    So get your telescopes out.

    If you watch the southeastern part of the sky Saturday night you might be able to see the shining Blue Moon while the Red Planet also beams a bright rusty-orange glow at the same time. Mars will be bright for the next couple of months.

    By the time Mars reaches opposition, it will have quadrupled in brightness since the beginning of April, according to EarthSky.org. 

    The last Blue Moon happened in July of 2015. The next one won’t happen until January of 2018. Traditionally, a Blue Moon is what people called an extra moon in a season. 

    Seasons typically only see three full moons, making 12 full moons in a calendar year. The fourth full moon in a season and 13ths for a year is rare.

    A warning: A Blue Moon is not actually blue. It is mostly bright white but can take on a bluish hue depending on the season and conditions.

    South Florida residents are expected to get a fair but not great opportunity to see what’s happening with the moon and Mars this weekend because of cloud cover.

    The forecast from AccuWeather.com predicts fair conditions for Blue Moon visibility on Saturday, but poor conditions for Mars visibility on Sunday.

    Is the Sun DISINTEGRATING? NASA spots monster hole open up on our star

    NASA has revealed that a massive hole, measuring more than ten per cent of the Sun's surface area, has opened up on our star.



    PUBLISHED: 20:06, Thu, May 26, 2016 | UPDATED: 01:37, Fri, May 27, 2016








    NASA
    The enormous hole takes up much of the top half of the star




    The remarkable footage was captured by the US space agency's Solar Dynamics Observatory between May 17 and 19.

    The video shows a giant dark area on the star's upper half, known as a coronal hole. 

    A NASA spokesman said: "Coronal holes are low-density regions of the sun’s atmosphere, known as the corona.

    "Because they contain little solar material, they have lower temperatures and thus appear much darker than their surroundings. 

    "Coronal holes are visible in certain types of extreme ultraviolet light, which is typically invisible to our eyes, but is colorised here in purple for easy viewing."

    NASA says the huge hole is actually not of great concern, but it remains unclear why the coronal holes actually form.

    But it does mean that large amounts of solar winds, that cause the Aurora Borealis or Northern Lights to form, have been blasted to Earth.

    These would weak havoc with our communications and blast us with cancer-causing UV rays, if it were not for the Earth's magnetosphere which shields us from them.

    The spokesman added: "These coronal holes are important to understanding the space environment around Earth through which our technology and astronauts travel. 

    "Coronal holes are the source of a high-speed wind of solar particles that streams off the sun some three times faster than the slower wind elsewhere. 




    Amazing Aurora Pictures from Alaska
    Fri, December 27, 2013

    Keen snapper Nolan Nitschke travelled to Alaska from his home in Bishop, California, after he and his friends worked out the time of year most likely to see the best aurora activity. And they werent let down - as the amazing array of colours danced across the Alaskan skies in a theatrical performance locals described as the most spectacular they had seen in over 30 years. Nolan and his pals spent the night photographing the stunning sights throughout a strong solar storm which he described as almost like tentacles uncontrollably waving through the air.





    "While it’s unclear what causes coronal holes, they correlate to areas on the sun where magnetic fields soar up and away, without looping back down to the surface, as they do elsewhere."

    It could also means the large holes are getting bigger.

    Last October, NASA released images showing a smaller hole, which was the size of 50 Earths, had formed in the same area.

    At that time, it was believed to have been one of the biggest ever recorded.

    SOLAR WIND SURROUNDS EARTH: This weekend, Earth is moving through a stream of solar wind flowing from a coronal hole in the sun. NOAA forecasters say there is a 35% chance of polar geomagnetic storms on June 12 as the solar wind surrounds our planet and gently buffets Earth's magnetic field. 


    DONUT OF LIGHT OVER COLORADO: It was faint, brief, and enormous. On June 8th, amateur astronomer Thomas Ashcraft photographed a 300 km-wide donut of light over a thunderstorm in southeast Colorado:
    "It only lasted about a millisecond," says Ashcraft, "but it was definitely there."

    This is an example of an ELVE (Emissions of Light and Very Low Frequency Perturbations due to Electromagnetic Pulse Sources).  First seen by cameras on the space shuttle in 1990, ELVEs appear when a pulse of electromagnetic radiation from lightning propagates up toward space and hits the base of Earth's ionosphere. A faint ring of light marks the broad 'spot' where the EMP hits. 

    ELVES often appear alongside red sprites. Indeed, Ashcraft's camera caught a cluster of sprites leaping straight up through the middle of the donut. "Play the complete video to see the sprites," says Ashcraft.
    ELVEs are elusive--and that's an understatement. Blinking in and out of existance in only 1/1000th of a second, they are completely invisible to the human eye. For comparison, red sprites tend to last for hundredths of a second and regular lightning can scintillate for a second or more. To catch an ELVE, a high-speed video camera is required. Stay tuned for more captures as thunderstorm season unfolds.

    UFO-SHAPED CLOUDS: On the evening of June 9th, a spectacular array of UFO-shaped clouds appeared above California's Eastern Sierra mountain range. The display was a sensation on social media as people in nearby valleys began posting pictures of the sunset-colored armada. One photographer, unlike the others, was in the mountains; ultrarunner Jeff Kozak of Bishop CA captured this edge-on view from 11,100 feet:
    "I was topping out on Morgan Pass at sunset when I looked south to see what I thought was The Mothership hovering over Mt Tom!" says Kozak.

    In fact, it was a lenticular cloud. Lenticular clouds form downwind of mountain ranges where the air organizes itself into starship-sized waves. Although they appear stationary, moist air is constantly moving through them, condensing at the apex of the wave. Wind sculpts the clouds into giant saucers and voilà--spaceships in the sky.

    SUBSIDING CHANCE OF STORMS: NOAA forecasters have downgraded the odds of a geomagnetic storm on June 17th to only 20% as Earth exits a stream of fast solar wind. Auroras are unlikely tonight. 


    FARSIDE SOLAR ACTIVITY: The Earth-side of the sun is quiet, with only two sunspots producing very low-level flares. The farside of the sun, however, is more active. On June 16th, the Solar and Heliospheric Observatory detected this CME billowing over the sun's northeastern limb:



    The source of the explosion is on the other side of the sun. It might be an active sunspot hidden from view by the body of the sun. If so, more CMEs are possible in the days ahead as the sunspot continues to flare. None of the CMEs, however, would be geoeffective until the active region turns toward Earth. For now, Earth-directed solar activity remains very low.

    Sunspots vanished almost two weeks ago and, as a result, solar activity is very low.

    GRAND CANYON 'BOW: To see a rainbow, all you need are sunlight and falling rain. Correction: that's all you need to see half a rainbow. Typical rainbows are at least 50% hidden below the horizon. To boost the fraction, add a canyon. David Blanchard saw almost 75% on July 1st: "Late afternoon thunderstorms gave way to sunlight just moments before sunset, resulting in this three-quarter circle rainbow," says Blanchard, who was standing on the south rim of the Grand Canyon when he took the picture.


    His photo shows that rainbows are not just arcs, but actually circles. Moreover, they are double circles. The interior or "primary rainbow" is caused by one reflection inside raindrops. The exterior or "secondary rainbow" is caused by two reflections. Turns out, you can learn a lot about rainbows by standing on a precipice.

    INCOMING SOLAR STORM: During the late hours of July 28th, a filament of magnetism erupted on the sun, slingshotting a cloud of plasma (CME) into space. Scroll past the movie of the CME to learn when it will hit Earth:



    NOAA analysts have computer-modeled the trajectory of this CME, and they say it is likely to strike Earth's magnetic field on August 1st. This is not a major storm cloud. Nevertheless, the impact could spark G1-class geomagnetic storms. High-latitude sky watchers should be alert for auroras when the CME arrives

    DOOMED COMET: The sun is about to swallow a comet. The doomed sungrazer appeared earlier today in images from the Solar and Heliospheric Observatory (SOHO):

    "This is one of the brightest Kreutz sungrazers we've seen over the past 21 yrs," says Karl Battams of the Naval Research Lab in Washington DC. "Awesome! "

    Kreutz sungrazers are fragments from the breakup of a single giant comet many centuries ago. They get their name from 19th century German astronomer Heinrich Kreutz, who studied them in detail. Kreutz fragments pass by the sun and disintegrate almost every day. Most, measuring less than a few meters across, are too small to see, but occasionally a bigger fragment like this one attracts attention. 


    The comet is vaporizing furiously and is not expected to survive much longer.

    Solar wind speed: 652

    QUIET WITH A CHANCE OF FLARES: Solar activity is low, however, it might not remain so. Big sunspot AR2585 is developed an unstable 'beta-gamma' magnetic field that harbors energy for moderately strong solar flares. NOAA forecasters estimate a 20% chance of M-flares on Sept. 3rd. 


    HIGH-SPEED SOLAR WIND SPARKS AURORAS: A stream of very fast moving solar wind is buffeting Earth's magnetic field this weekend, and this is causing geomagnetic storms around the poles. A twilight display in Lofoten, Norway, on Sept. 3rd prompted one photographer to move his dinner table outside:



    "I had a plan to invite my dear for a glass of wine this evening," says June Grønseth. "Due to a burst of light from the sky, I just had to change the seating from inside to outside my home. Here in Lofoten, we are really enjoying life."


    The solar wind is flowing from an unusually large coronal hole on the sun, shown here in an image from NASA's Solar Dynamics Observatory:
    Coronal holes are regions in the sun's atmosphere where the magnetic field opens up and allows solar wind to escape. This hole is spewing a stream of solar wind so broad, it could influence Earth's space environment for days to come. High-latitude sky watchers should remain alert for auroras throughout the weekend. 

    SUNSET PLANETS: Last night, careful observers of the sunset may have noticed a close encounter between Jupiter and crescent Moon. For many, the meeting was blocked by low hanging clouds. "Flying at 39,000 feet definitely improved visibility," says Mark Staples, who took this picture from the window seat of an airplane over South Carolina:

    "We were flying over the remains of Hurricane Hermine," says Staples. "It was hard to get a clear, motionless, undistorted pic thru the airplane window, but the storm clouds made for a spectacular sunset."

    SLACKENING SOLAR WIND: Earth is exiting a fast-moving stream of solar wind that sparked bright auroras over the weekend.  As a result, NOAA forecasters have lowered the odds of geomagnetic storms on Sept. 5th to only 20%. 

    'AURORA SEASON' IS UNDERWAY: Around the Arctic Circle, the end of summer is greeted with mixed feelings. The midnight sun sets, taking its cheerful rays below the horizon. The air might not be warm again for months. The onset of cold, however, brings something wonderful to behold. This

    "A new season with Northern Lights has started in northern Norway," reports photographer Kristin Berg, who took this picture on Sept. 2nd from Tromsø. "What a night! "

    Northern Lights are returning to the Arctic for two reasons. The first is simple: It's getting dark. The exit of the midnight sun is leaving velvety-dark skies where geomagnetic storms can paint their colors. The second is a little more complicated. During the weeks around equinoxes, the tilt of the interplanetary magnetic field favors geomagnetic storms. Even gentle gusts of solar wind can spark bright outbursts of light.

    Solar storm heading towards Earth threatening to break your Sky TV and mobile phones


    Modern-day Britain could go into meltdown after scientists forecast the solar storm to hit between now and Friday which could wreak havoc with technology.

    Solar storms affect Earth’s technology as radiation is thrown at the planet from the Sun.

    While humans are protected from the radiation by the atmosphere, the rays can heat the outer atmosphere, causing it to expand which can affect satellites in orbit. That could lead to a lack of GPS navigation, mobile phone signal and satellite TV such as Sky.

    Furthermore, higher currents in the magnetosphere – the Earth’s magnetic field – could lead to a surge of electricity in power lines, which can blow out electrical transformers and power stations leading to a temporary loss of electricity in a region – although this usually only occurs in areas that are in high altitude.

    The US National Oceanic and Atmospheric Administration (NOAA) says a coronal hole has opened on the Sun, leading to a stream of solar particles hurtling towards Earth.

    According to SpaceWeatherLive: “The magnetic field of a coronal hole is different than the rest of the Sun. Instead of returning to the surface, these magnetic field lines stay open and stretch out into space.”

    As a result, Earth is expected to be hit by a swarm of particles in the coming days which, on a better note, could cause the Northern Lights to be visible.

    Mauro Messerotti, from the University of Trieste the National Institute of Astrophysics (INAF) warned that the hole “extends for about 30 per cent of the disk of the sun” and that the structure “may persist for more than a month because these holes sometimes last for more than one full rotation of the sun, which lasts 28 days.”

    http://www.express.co.uk/news/science/715472/Solar-storm-Earth-break-Sky-TV-mobile-phones

    A HUGE solar storm is heading towards Earth which could leave us without mobile phones, satellite TV and even electricity.
    GEOMAGNETIC STORM TODAY: As predicted, a high-speed stream of solar wind is buffeting Earth's magnetic field today. Since it arrived on Sept. 27th, the stream has sparked G1- and G2-class geomagnetic storms and bright auroras around the Arctic Circle. NOAA forecasters say the storms could intensify on Sept. 28th as the stream reaches peak speeds in excess of 700 km/s. High-latitude sky watchers should remain alert for auroras.

    The Aurora and Milky Way over Noss Head in Caithness, Scotland last night. Parts of the world are expected to light up in a green glow tonight, as a strong solar storm continues. The storm is caused by a hole in the outermost layer of the sun, opening the magnetic field up to stretch further than usual, which results in a gradual increase in the solar wind

    The British Geological Survey, Aurorawatch UK and US body Space Weather Prediction Centre have all reported heightened opportunities of spotting the aurora, because a hole in the sun's outer layer is facing Earth.

    'A G2 (Moderate) Geomagnetic Storm Alert was issued at 2048 UTC (4:48 pm ET) on 28 September as effects from a large coronal hole high speed stream continue,' the National Oceanic and Atmospheric Administration (NOAA)' Space Weather Prediction Centre said.
    It added, however, that the storm was unlikely to have an impact on electrical infrastructure or power grids.

    The barrage of charged particles from the sun is expected to continue until Saturday when the activity will die down, space weather reports have said.

    The storm, which started yesterday, has already treated some people in the north of Scotland to a magnificent display.

    The British Geological Survey (BGS) told the BBC: 'A very large, centrally located coronal hole has rotated around the sun's surface so that it is now facing the Earth.

    'This means that a stream of fast solar wind is currently hitting the Earth's magnetic field and causing an increase in geomagnetic activity.'
    BBC Weather said the aurora could be visible from east Scotland, Northern Ireland and northern England.

    Solar wind speed: 523.5 km/sec

    POLAR MAGNETIC STORMS: Minor G1-class geomagnetic storms are underway on Oct. 4th as Earth slowly exits a high-speed stream of solar wind. Polar sky watchers should remain alert for auroras: realtime photo gallery.

    RED AIRGLOW OVER EASTER ISLAND: Not every colorful light in the night sky is an aurora.  Especially not in the South Pacific. Yuri Beletsky was on a beach in Easter Island, Chile, two nights ago when the starry canopy turned red:

    "There was no fire," says Beletsky. "This is an amazing display of airglow."

    Airglow is aurora-like phenomenon caused by chemical reactions in the upper atmosphere. Human eyes seldom notice the faint glow, because it is usually very faint, but it can be photographed on almost any clear dark night, anywhere in the world.

    Beletsky is a veteran photographer of airglow, having captured it dozens of times from sites in Chile and the South Pacific. "The intensity of airglow varies, and sometimes it can be more prominent, as it was on Oct. 2nd," he says.

    The curious thing about Beletsky's photo is not the intensity of the airglow, but rather its color--red. Airglow is usually green, the color of light from oxygen atoms some 90 km to 100 km above Earth's surface. Where does the red come from? Instead of oxygen, OH can produce the ruddy hue. These neutral molecules (not to be confused with the OH- ion found in aqueous solutions) exist in a thin layer 85 km high where gravity waves often impress the red glow with a dramatic rippling structure.

    GEOMAGNETIC STORMS UNDERWAY: Geomagnetic activity is intensifying as Earth passes through the wake of a CME that hit our planet yesterday. Currently, a G1-class storm is in progress. Polar sky watchers should be alert for auroras on Oct. 13-14. Solar Wind Speed: 427.5 km/sec

    WHAT'S NEXT? On Oct. 15th, another disturbance is expected to hit Earth's magnetic field.  This time it's coming from a coronal hole--a gap in the sun's atmosphere from which solar wind flows:




    At the leading edge of the emerging solar wind stream is a co-rotating interaction region (CIR)--that is, a transition zone between slow- and fast-moving solar wind.  Shock waves and density gradients in CIRs often go a good job sparking auroras, so when it arrives on Oct. 15th polar auroras are likely.

    MAGNETIC STORMS LIKELY THIS WEEK: NOAA forecasters have boosted the odds of polar geomagnetic storms on Jan. 4th and 5th to 65% as a stream of solar wind approaches Earth. The hot wind is flowing from a large hole in the sun's atmosphere. This image, from NASA's Solar Dynamics Observatory, shows the yawning structure almost directly facing Earth on Jan. 3rd:

    Coronal holes are regions where the sun's magnetic field peels back and allows solar wind to escape.  The stream of wind emerging from this coronal hole recently blew past NASA's STEREO-A spacecraft with peak speeds exceeding 700 km/s. Similar high speeds are likely when the stream reaches Earth on Jan. 4th and 5th.  

    Residents of the Arctic should expect G1-class geomagnetic storms and bright auroras in the nights ahead.

    Massive Coronal Hole Faces Earth / Solar Storm Watch for 4 and 5 January 2017
    Published on Jan 3, 2017

    A large hole in the Sun's atmosphere. Stretching more than halfway across the face of the sun, a large hole in the sun's atmosphere is facing Earth.

    That massive coronal hole system that faced us 8 and 4 weeks ago is back. For the third time in a row it survived its trip around the far side of our star. The Big Freeze and uptick in earthquakes occurred 4 weeks ago as well.

    Nemesis Maturity is in my opinion the BEST space-weather Utube author, hands-down.

    Very informative, great visuals, and no strange narratives--JUST PRINTING--that is less distracting.

    We have also had our #37 and #38 large gamma ray burst detected from the Swift Telescope on l-01-2017 (which
    is going to ADD to the radiation/GRB intensity of the solar winds.) Here are the links:

    Heating of the Troposphere will push more cold down on us as well.

    Intense.

    CHANCE OF STORMS: NOAA forecasters estimate a 65% chance of G1-class geomagnetic storms on Jan. 5th as Earth moves into a stream of fast-moving solar wind. The source of the wind is a large hole in the sun's atmosphere. Arctic sky watchers should be alert for aurorason Thursday night.

    Solar wind speed: 702.3 km/sec density:
