A comet is diving into the sun today. Just discovered by comet hunters Michal Kusiak of Poland and Sergei Schmalz of Germany, the icy visitor from the outer solar system is expected to brighten to first magnitude before it disintegrates on Sept. 14th.
New sunspot AR1295 is emerging over the sun’s northeastern limb and crackling with solar flares. The strongest so far, a C9.9-category blast, did something remarkable. Click on the arrow to watch an extreme ultraviolet movie from NASA’s Solar Dynamics
The first of several CMEs en route to Earth struck our planet’s magnetic field on Sept. 9th around 1130UT. The impact sparked a strong (Kp=7) geomagnetic storm, which is now subsiding. Last night Northern Lights were spotted in the United States as far south
UPDATE: The Geomagnetic Storm has subsided over the past few hours. However, the solar wind remains energized and occasional pulses of activity are expected for another 24 hours. Region 1283, the responsible party back at the Sun, decayed today. The Geomagnetic Storm
A polar geomagnetic storm (Kp=5) is in progress following the impact of a CME around 1100 UT on Sept. 9th. This could be the first of several hits from a series of CMEs expected to reach Earth during the weekend. High-latitude sky watchers should be alert for auroras
On Sept 8th around 2300 UT, the SOHO and STEREO spacecraft detected a significant CME emerging from the farside of the sun. Earth is not in the line of fire, but the planet Mercury is. Analysts at the Goddard Space Weather Lab estimate that the cloud will reach the

A strong M-Class flare registering M6.7 took place at 15:46 UTC around active Sunspot 1283. Stay tuned for any further updates. (SolarHam)On Sept. 8th at 1546 UT, sunspot 1283 unleashed an M6-class solar flare. This continues the active region’s 3-day trend of
This week's sharp increase in solar activity has turned the Sun into a radio transmitter. Bursts of shortwave static are coming from the unstable magnetic canopy of sunspot 1283. Yesterday in New Mexico, amateur radio astronomer Thomas Ashcraft recorded some…
A strong X2.1 Class Solar Flare took place at 22:20 UTC Tuesday and was centered around Sunspot 1283. Another CME now looks to have resulted (watch it). A Type II and Type IV sweep frequency event occurred as well as a TenFlare (10.7cm Radio Burst). Proton Levels are
