On June 7th at 0641 UT, magnetic fields above sunspot complex 1226-1227 became unstable and erupted. The resulting blast produced an M2-class solar flare, an S1-class radiation storm, and an unbelievable movie:Much of the plasma thrown up by the blast simply fell
At 06:41 UTC today the Sun unleashed an M2-class solar flare from arround the sunspot complex 1226-1227. Substantial Coronal Mass Ejection was observed and was visually spectacular. The large cloud of particles mushroomed up and fell back down looking as if it
Amateur astronomers around the world are reporting strong activity on the limb of the sun. The prominences on June 4th were gigantic. Prominences are clouds of hot plasma
A sharp gust of solar wind hit Earth's magnetic field at approximately 20:30 UTC on June 4, 2011. High-latitude sky watchers in both hemispheres should be alert for auroras. Solar windspeed: 495.9 km/secdensity: 2.6 protons/cm3 Planetary K-indexNow: Kp= 5…
A solar wind stream is buffeting Earth’s magnetic field, sparking Southern Lights around the Antarctic Circle. Ian Stewart sends this picture to SpaceWeather.com from a jetty near Hobart, Tasmania:”Not long after sunset a friend rang to ask whether a faint arc of
The quiet sun is waking up. New sunspot 1226 emerging over the sun’s southeastern limb is crackling with strong C-class solar flares. So far none of the blasts has been geoeffective, but this could change in the days ahead as the active region turns toward
British Defence Secretary Liam Fox will next week attend a summit of scientists and security advisers who believe the infrastructure that underpins modern life in Western economies is potentially vulnerable to electromagnetic disruption.Blogger’s and scientists
A comet dove into the sun on May 11th and seemed to trigger a massive eruption. Watch the movie, then scroll down for further discussion.
A comet goes in; a CME comes out. Coincidence? Probably, yes, the sequence was coincidental. The comet disintegrated
A comet just discovered by amateur astronomer Sergey Shurpakov is diving past the sun today, and it will probably not survive. Click here to view a movie of the death plunge recorded by the Solar and Heliospheric Observatory–and check back for updates in the hours
A sunspot located just behind the sun’s eastern limb erupted during the waning hours of May 9th, hurling a spectacular coronal mass ejection into space: movie. NASA’s Solar Dynamics Observatory photographed hot magnetic loops towering over the edge of the sun in the
