M1.2 solar flare, C7.0 solar flare

A new sunspot region is now rotating into view of the north-east limb. It should receive sunspot number 2672 later today or tomorrow. This could be yet another sunspot region with potential to produce strong solar flares as it made itself known this night with an M1.2 solar flare that peaked at 01:52 UTC.

Coronal hole faces Earth

A southern extension of the northern hemisphere polar coronal hole is now facing Earth. It extended far enough towards the south to trigger our automated coronal hole detection system.

New active region producing C-class flares

A new and unnumbered active region is now rotating into the earth-facing solar disk. It is new active region that only started to develop about 24 hours ago based on STEREO Ahead EUVI footage.

Sunspot region 2670

Wednesday, 2 August 2017 - 16:49 UTC

Sunspot region 2670

Old sunspot region 2665 which caused a couple of large far side eruptions has now rotated back onto the earth-facing solar disk. It has received sunspot region number 2670 from the NOAA SWPC. Due to the activity this sunspot region displayed while it was on the far side, hopes were high for its return. So what is left of this group and should we expect more solar flares?

Coronal mass ejection arrival

The anticipated coronal mass ejection from the M2.4 solar flare has arrived at Earth. It arrived at DSCOVR at 05:15 UTC which is about 9 hours earlier than we expected, and more than 15 hours earlier than the NOAA SWPC expected.

Earth-directed coronal mass ejection

Sunspot region 2665 erupted this night with an M2.4 (R1-Minor) solar flare that peaked at 02:09 UTC. It was a long duration and highly eruptive event. More information about the solar flare can be found in the article that we wrote this morning.

Eruptive M2.4 solar flare

Eruptive M2.4 solar flare

Decaying sunspot region 2665 (Beta, S07W31) produced a very long duration M2.44 solar flare that is still in progress at the time of writing. Indeed a big surprise as its magnetic layout remains rather simple and that means such a solar flare was very unlikely to happen.
