01:22 UT – AR12113 produced an M1.2 flare that peaked in GOES X-ray at 00:26 UT Type II radio emission was detected at 00:29 UT. This emission is associated with a solar eruption and typically indicate a coronal mass ejection […]

There are two main active regions (ARs 11967/11968) on the sun and both are giving a moderate show. AR11967 continues to produce C- and M-level events, including an M3.0 flare at 07:14 UT Feb. 1, 2014. The region continues to show signs […]

The sun has been really active lately. SDO gives us an amazing view of this activity in many different wavelengths of light. This also shows us the sun’s atmosphere in many temperatures ranging from ~4500 Kelvin or 7600 degrees Fahrenheit […]

A long duration M3.3 flare with a beautiful eruption and CME! Active region AR11818 produced a flare peaking in X-ray at 18:24 UT (2:24 pm EDT). The eruption produced extended X-ray emission with another flare, ~M1.5 after the initial eruption […]

Wiggly Jiggly Loops by 4 flares from an evolving sunspot AR11748 showed us some exciting yet basically benign activity. A little image processing helps us really see certain aspects of the activity. Keep an eye out for wiggling loops set […]

A new active region peaking around the edge of the sun released an X-class solar flare At 2:17 UT or 10:17 pm EDT, an active region that has not yet rotated into view produced an X1.7 solar flare on May […]
