The magnetic canopy of sunspot 1190 erupted on April 15th, producing an M-class solar flare (SDO movie). The brief blast did not, however, hurl a cloud of plasma toward Earth. NOAA forecasters estimate a 55% chance of more M-flares during the next 24 hours.
Newly-arriving data from NASA’s STEREO probes suggest that a coronal mass ejection (CME) might be heading toward Earth. The source of the cloud appears to be sunspot complex 1185-1186, which experienced an episode of magnetic instability during the early hours of April
NASA’s STEREO probes are monitoring strong activity on the far side of the sun. A spectacular CME erupted during the early hours of April 8th apparently from old sunspot AR1176. This is the second day in a row that the active region has hurled massive clouds into
NASA twin STEREO spacecraft observed a spectacular coronal mass ejection launched from the vicinity of decaying sunspot 1176 on April 3rd around 0500 UT. The blast was not Earth directed. Nevertheless, there is a chance that the expanding cloud will deliver a glancing
A big sunspot is emerging over the sun’s southeastern limb, and it is crackling with activity. NASA’s Solar Dynamics Observatory recorded a surge of extreme ultraviolet radiation from the sunspot’s magnetic canopy on March 21st:This appears to be the return of old
A huge filament of magnetism and hot plasma blasted off the sun’s southwestern limb on March 19th around 1200 UT. The eruption was not Earth-directed, but it did attract plenty of attention on our planet. Many amateur astronomers in Europe witnessed the blast and said
While we are still on impact of CME from X-flare events from March 9th, the sun got new M-class flare eruption.Effects from the 07 March CME was slowly subsiding during day one (11 March), but the arrival of a coronal hole high speed stream is expected to become
UPDATE:A coronal mass ejection (CME) hit Earth’s magnetic field on March 10th around 0630 UT. Solar wind conditions, post-impact, are favorable for geomagnetic activity.March 9th ended with a powerful solar flare. Earth-orbiting satellites detected an X1.5-class
A coronal mass ejection (CME) exploded from the vicinity of sunspot 1164 during the late hours of March 7th. It lept away from the sun traveling some 2200 km/s, making it the fastest CME since Sept. 2005. A movie of the cloud prepared by Karl Battams of the Naval
Several M-Class flares (7) took place during the day on Monday. Sunspot 1165 which is located in the southern hemisphere is in the process of rotating onto the western limb and will soon be out of direct earth view. Sunspot 1164 which is in the northern hemisphere
