Sunspot region 2740 has been much less active as it has been decayed the past few days. But that didn't mean it went totally quiet. A minor eruption near the this sunspot region took place around midnight UTC yesterday and launched a faint partial halo coronal mass ejection that could arrive at Earth in a few days from now.

The minor G1 geomagnetic storm was reached earlier today at 02:20 UTC. This is caused by a coronal mass ejection passage that brings a persistent southward pointing magnetic field with it. This coronal mass ejection that we are seeing at Earth right now is likely the coronal mass ejection that we posted about on 8 May.

A faint halo coronal mass ejection with a possible earth-directed component has been detected in coronagraph imagery from SOHO/LASCO.

Almost an M-class solar flare! Sunspot region 2740 (Beta-Delta) produced a very impulsive C-class solar flare this morning at 05:10 UTC. The solar flare peaked at an X-ray flux of C9.97 which is just shy of the M-class threshold. The eruption was associated with an Type II Radio Emission and several more C-class solar flares occurred as the day progressed.

Not much to report on the earth-facing side of the moment but the Sun's far side has sprung back to life with two distinct areas firing off eruptions.

Aurora season is now rapidly coming to an end for high latitude sky watchers in the northern hemisphere but the night skies for our friends in the southern hemisphere are only getting darker and darker. Good news for you as we have a coronal hole facing our planet today which is sending a high speed solar wind stream towards our planet.

Space weather has been very quiet lately with not much interesting to report on. There haven't been any sunspot regions or solar eruptions worth mentioning and also here on Earth we've been having quiet geomagnetic conditions. This could however change in the near future as we have a southern hemisphere coronal hole facing our planet today. Those of you who follow us on Twitter or have the SpaceWeatherLive iOS/Android app have likely seen the automated coronal hole detection alert.

With the introduction of GOES-16, the NOAA SWPC provides us with yet another valuable solar watching sentinel which will undoubtedly be of great use when solar cycle 25 begins.

Yesterday's article about NASA launching a satellite to close solar coronal holes in order to make human missions to Mars possible was of course the SpaceWeatherLive April Fools prank. It was entertaining to see all of your responses and a couple of you even fell for the prank. Great fun! If you missed the article and like a good laugh be sure to click here and give it a read.

A new sunspot region that received sunspot number 2736 earlier today erupted with a long duration C-class solar flare. The solar flare peaked at 11:18 UTC and reached a maximum X-ray flux of C4.8. The eruption was associated with a Type II radio sweep which indicated straight away that this event was likely to be eruptive and thus launched a coronal mass ejection into space.
