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 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
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 low level M-Class flares have taken place around each of the big three regions 1164, 1165 and 1166 during the early parts of Monday. The largest one of these thus far was an M1.8 around Sunspot 1165. Sunspot 1165 will begin to rotate onto the western limb over
M3.6 solar flare occurred on February 24 near the solar esatern limb and blew out a gorgeous CME plasma waves that swirled and twisted over a 90-minute period. Some of the material blew out into space and other portions fell back to the surface. This event was
Space weather could pose serious problems here on Earth in the coming years, National Oceanic and Atmospheric Administration warned today.
NOAA administrator Jane Lubchenco warned at the annual meeting of the American Association for the
IMPACT! A CME hit Earth’s magnetic field at approximately 0100 UT on Feb. 18th (8:00 pm EST on Feb. 17th). The impact was not as strong as expected considering the cloud’s
Britain should experience spectacular Northern Lights displays from Thursday due to a large solar storm which could disrupt communication networks, the British Geological Survey (BGS) said. “Since February 13 three energetic solar flares have erupted on the
A series of coronal mass ejections (CMEs) en route to Earth from sunspot 1158 will buffet our planet's magnetic field during the next 24-48 hours. NOAA forecasters estimate a 45% chance of geomagnetic activity on Feb. 17th.
