Earth is entering a stream of solar wind blowing ~500 km/s, and the encounter is stirring up geomagnetic activity around the Arctic Circle. The solar wind data (velocity and proton density) presented on spaceweather.com are updated every 10 minutes. They are derived
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
During the past 24 hours, aurora displays have descended as far south as Wisconsin, Minnesota, and Michigan in the United States. Earth’s magnetic field is still reverberating from a CME strike on March 10th.Solar wind conditions favor more geomagnetic storming in
A coronal mass ejection (CME) hit Earth’s magnetic field on March 10th around 0630 UT. The impact, albeit weak, did provoke geomagnetic activity around the poles.Planetary K-indexNow: Kp= 5 storm24-hr max: Kp= 5 stormNewly-arriving coronagraph data from the Solar
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
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
