Old sunspot region 2665 which caused a couple of large far side eruptions is now rotating back onto the earth-facing solar disk.

An absolutely massive far side coronal mass ejection can now be seen on both STEREO and SOHO coronagraph imagery.

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.

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.

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.

An M1.38 solar flare took place this night that peaked at 03:18 UTC. It came from the only numbered sunspot region on the earth-facing solar disk: sunspot region 2665.

Now that is what we call a surprise! Departing sunspot region 2664 which is now behind the west limb just produced an M-class solar flare! Yes, you heard that right. It was an impulsive M1.3 solar flare that peaked at 16:15 UTC. This was the first M-class solar flare since an M5.8 solar flare that took place on 3 April. That is today exactly three months ago!

A coronal mass ejection shock arrived at DSCOVR today at 16:27 UTC and it increased the total strength of the interplanetary magnetic field to a respectable 18nT.

Yes, a sign of life from your SpaceWeatherLive staff! It has been a very quiet space weather period the past few weeks with pretty much no geomagnetic or solar events worth mentioning. We did reach the minor G1 geomagnetic storm levels briefly 2 weeks ago but that was nothing too spectacular. Our Sun is even more quiet: its been almost 3 months ago since we last had an M-class solar flare and the last C-class solar flare was also a solid 3 weeks ago. Does that mean you are reading a news article without any news? Not exactly as a possibly interesting eruption took place yesterday that could give us some aurora in a few days from now.

We're in a really quiet space weather period at the moment and there were no major space weather events the past week.

A lot of people come to SpaceWeatherLive to follow the Sun's activity or if there is aurora to be seen, but with more traffic comes higher server costs. Consider a donation if you enjoy SpaceWeatherLive so we can keep the website online!
