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 coronal mass ejection arrived at our planet yesterday and managed to cause an unexpectedly strong geomagnetic storm. The strong G3 geomagnetic storm threshold was reached today at 04:19 UTC.

A weak coronal mass ejection (CME) was launched yesterday by an eruption near the center of the earth-facing solar disk. The resulting coronal mass ejection might have an earth-directed component.

The NOAA SWPC had a moderate G2 geomagnetic storm watch in effect during the past few days but we unfortunately haven't even reached the minor G1 geomagnetic storm level. The G2 geomagnetic storm watch from the NOAA Space Weather Prediction Center was a result of a possible coronal mass ejection (CME) impact, something we indeed never mentioned on the site or on our social media pages. We did not believe this solar storm had an earth-bound component so choose to not mention it, a strategy that proved to be the right one. A minor G1 geomagnetic storm was however predicted due to a coronal hole solar wind stream but the stream was weaker than expected and only caused active geomagnetic conditions (Kp4) on 15 May. We are however getting another chance to reach geomagnetic storm levels thanks to yet another coronal hole.

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!
