A long duration B7.5 solar flare was observed at 07:30 UTC on October 5. Post eruption loop structures were observed in GOES SXI imagery in the vicinity of Region 1584. A partial halo CME was first observed in SOHO/LASCO C3 imagery at 07:30 UTC and STEREO Ahead
Sunspot 1583 on the western limb produced an M1.3 flare on Sept. 30 at 04:33 UTC. Region 1583 had grown rapidly in the past 24 hours, however it is only hours away from rotating off the solar disk and out of view. SIDC and NOAA/SWPC expect mostly eruptive conditions
NOAA/SWPC reported that the G1 (minor) Geomagnetic Storm has ended with the return of normal solar wind conditions. Currently solar winds blow at speed of 419.1 km/sec. Earthbound proton levels are now below the S1 Minor Radiation Storm threshold and geomagnetic
Solar filament eruption on August 31 generated at least two potentially Earth directed CME clouds. Earth was hit by first CME shock, observed in the solar wind around 11:20 UTC. The impact induced significant ground currents in northern Scandinavia and
NOAA/SWPC have determined that the CME from Active Region 1402 near disk center from the latest M3 solar flare will likely pass above (north) of Earth. This glancing blow will cause just G1 (Minor) Geomagnetic Storm activity. We can expect first signs starting from
The dark vertical coronal hole, about 120,000 km wide and more than a million km long, stretches in the center of the Sun. A solar wind stream flowing from the indicated coronal hole should reach Earth on Jan. 16-17, possibly sparking auroras at

Earth is entering a minor solar wind stream that could spark auroras around the Arctic Circle. High-latitude sky watchers should be alert for Northern Lights tonight.Solar windspeed: 452.2 km/secdensity: 1.5 protons/cm3The Radio Sun10.7 cm
Officially, the odds of a geomagnetic storm on Nov. 24th were small but dedicated aurora watchers still had some opportunity to take some nice images of beautifull sky game. Auroras have been flickering around the Arctic Circle for several days. These displays are not
NOAA forecasters have upgraded the chance of X-class solar flares today to 20%. The source would be AR1339, one of the biggest sunspots in many years. The active region rotated over the sun’s eastern limb two days ago and now it is turning toward Earth.The Radio
