A Gash in the Sun's Atmosphere


Source - Space Weather News for Feb 19, 2017: http://spaceweather.com

A GASH IN THE SUN'S ATMOSPHERE: An unusually wide and sinuous hole has opened in the sun's atmosphere, and it is stretching like a gash across the sun's southern hemisphere. A roughly fan-shaped stream of solar wind flowing from the hole is gently buffeting Earth's magnetic field, and it could keep polar magnetic fields in an unsettled state for the rest of February.  Long range forecasts suggest the month could end with a moderately strong (G2-class) geomagnetic storm. This is all good news for Arctic sky watchers, who can expect regular episodes of Northern Lights in the nights ahead.

Mother's Day Geomagnetic Storm


Source - Space Weather News for May 8, 2016: http://spaceweather.com

MOTHER'S DAY GEOMAGNETIC STORM: Surprise! Sunday, May 8th, began with a strong G3-class geomagnetic storm that sparked beautiful auroras around both poles.  Northern Lights were spotted in at least half a dozen US states. Meanwhile, at the other end of the planet, Southern Lights lit up the skies and snowy landscape of Antarctica.

Double CME Hits Earth, Sparks Auroras

Source - Space Weather News for June 17, 2012: http://spaceweather.com

As predicted, a double CME hit Earth's magnetic field on June 16th.  The impact strongly compressed Earth's magnetosphere, exposing geosynchronous satellites to solar wind plasma and sparking more than 24 hours of geomagnetic storms.  (The storms are still in progress as this alert is being written during the middle hours of June 17th.) In the United States, Northern Lights have descended as far south as Wisconsin, Washington, Minnesota, and the Dakotas.  Southern hemisphere observers are also reporting colorful aurora australis.  Check http://spaceweather.com for photos and updates.

Geomagnetic Storm on April 30th

Source - Space Weather News for April 30, 2011: http://spaceweather.com

GEOMAGNETIC STORM: A solar wind stream hit Earth's magnetic field during the early hours of April 30th, sparking a G1-class geomagnetic storm. Northern Lights descended as far south as Michigan in the United States. High-latitude sky watchers should remain alert for auroras (http://spaceweatherphone.com) tonight as the solar wind continues to blow. Photos of the April 30th display are highlighted on today's edition of http://SpaceWeather.com.

TRACK THE SPACE SHUTTLE: Space shuttle Endeavour is scheduled to lift off from the Kennedy Space Center on Monday, May 2nd, on a two-week mission to the International Space Station. The shuttle and station will make many visible passes over Europe and North America during the mission--the trick is knowing when to look. You can turn your cell phone into a field tested shuttle tracker by downloading our Simple Flybys app. Details at http://simpleflybys.com

Geomagnetic Storm on April 12

Source - Space Weather News for April 12, 2010: http://spaceweather.com

GEOMAGNETIC STORM: A solar wind stream hit Earth's magnetic field on April 12th, sparking Northern Lights as far south as Michigan and Minnesota in the USA. At the time of this alert (April 12 @ 1600 UT), the G1-class event is still underway. Images and updates are available at http://spaceweather.com .

Auroras Invade the USA

Source - Space Weather News for March 11, 2011: http://spaceweather.com

AURORAS IN THE USA: A coronal mass ejection (CME) hit Earth's magnetic field on March 10th. The impact set off a G1-class geomagnetic storm and sent Northern Lights rippling over the US-Canadian border into states such as Wisconsin, Minnesota, and Michigan. Sky watchers who hadn't seen auroras in years captured beautiful photos of green and purple streamers. This is another sign that Solar Cycle 24 is heating up. Check http://spaceweather.com for photos and updates.

Storms on Saturn and Earth

Source - Space Weather News for Dec. 28, 2011: http://spaceweather.com

BIG STORM ON SATURN: Got a telescope for Christmas? Point it at Saturn. A giant storm even brighter than Saturn's rings is raging through the planet's cloudtops. Amateur images and sky maps are featured on today's edition of http://spaceweather.com.

GEOMAGNETIC STORM IN PROGRESS: At the time this alert is being written (mid-day UT on Dec. 28), a polar geomagnetic storm is in progress (Kindex=5). Observers report electric currents in the ground and intensifying Northern Lights over Scandinavia. High-latitude sky watchers should be alert for auroras: http://spaceweathertext.com .

Solar Blast Just Misses Earth

Source - Space Weather News for August 8, 2010: http://spaceweather.com

SOLAR BLAST JUST MISSES EARTH: On Saturday, August 7th, magnetic fields around sunspot 1093 erupted. NASA spacecraft and many amateur astronomers photographed the blast, which produced a strong M1-class solar flare and hurled a coronal mass ejection (CME) into space--apparently just missing the sun-Earth line. The explosion also made whooshing sounds in the loudspeakers of some shortwave radios. Visit http://spaceweather.com for audio recordings and movies of this latest solar event.

AURORA RECAP: Last week's geomagnetic storm sparked Northern Lights as far south as Iowa in the United States, and some nice Southern Lights over Antarctica. For the latest images, start browsing here: http://www.spaceweather.com/aurora/gallery_01aug10_page4.htm
