NASA's Solar Dynamics Observatory (SDO) released video of Active Region 1785 – one of the largest sunspot groups this year, traveling across the Earth facing solar disk in period from July 3 – July 11, 2013. AR 1785 is now out of Earth view, moving onto
Sunspots are emerging at several locations around the solar disk, peppering the Earth-side of the sun with active regions. Of particular interest is fast-growing sunspot 1282, shown here in an August 31st snapshot from NASA’s Solar Dynamics Observatory:AR1282 has
A big new sunspot is emerging over the sun's northeastern limb. AR1271 has at least four dark cores and it is crackling with small flares. The sunspot's entrance was captured in this 24-hour movie from the Solar Dynamics Observatory: NOAA forecasters…
Active sunspot 1263, which just two days ago produced the most powerful solar flare of the new Solar Cycle (an X7), has left the Earthside of the sun. It is now beginning a two week transit across the solar farside. We can still see signs of its ongoing activity,
Sunspot 1261 is at it again, this time producing a strong M9.3 Solar Flare at 03:57 UTC Thursday morning. It also turns out that yet another Coronal Mass Ejection (CME) was produced and you can see it in the still image below captured by STEREO Ahead.Proton Levels are o
On June 7, 2011, Earth-orbiting satellites detected a flash of X-rays coming from the western edge of the solar disk. Registering only “M” (for medium) on the Richter scale of solar flares, the blast at first appeared to be a run-of-the-mill eruption- that is, until
During the early hours of July 9th, a Coronal Mass Ejection (CME) billowed away from new sunspot 1247. A preliminary analysis of data from NASA's twin STEREO-A and -B spacecraft suggests that the flank of the CME could hit Earth's magnetic field sometime on July
