Sun woke up after three years of sleep. Several powerful solar flares occurred in recent months, with a February 14 blast as the strongest and  the most powerful outburst in more than four years. Considering surface of Sun dotted with sunspots and recent activity,

Eruption of magnetic canopy of sunspot 1190

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.

Subsiding geomagnetic storm (April 13,2011)

A geomagnetic storm that sparked auroras around the Arctic Circle and sent Northern Lights spilling over the Canadian border into the United States on April 12th is subsiding. At the height of the display, Shawn Malone took this picture from the shores of Lake

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

Strong activity on the far side of the sun

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

The solar wind is blowing past earth at elevated levels today and combined with a south tilting Bz, is stirring up geomagnetic storming at high latitudes. C-Class flare activity is now taking place towards the new sunspot regions just to the east of Sunspot 1185. Keep

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

Earth is entering a stream of solar wind

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
