The Sun is full of surprises. Just when you least expect it she produces two M-class solar flares: M1.1 at 18:37 UTC and a very long duration M2.2 solar flare that peaked around at 21:26 UTC.
The source of these solar flares is located behind the east limb and as a result, these solar flares might have been stronger than the M1 and M2-classes as recored by GOES-15. There are two familiar sunspot regions about to return and one of them is likely the source of these solar flares: old sunspot region 2173 or 2172. A coronal mass ejection was likely launched but it will of course be directed away from Earth.

Geomagnetic conditions are currently active (Kp4) according to the Wing-Kp index following favourable solar wind and IMF conditions likely related to a coronal hole high speed stream. Be sure to read our previous news item for more information. Conditions remain favourable for active (Kp4) geomagnetic conditions with a chance for minor G1 geomagnetic storming conditions in the hours ahead so also sky watchers in the northern parts of the United States should be alert for aurora. The NOAA SWPC has confirmed that G1 geomagnetic condtions have been reached with the observed Wing-Kp index being slightly below that value.
In Europe, aurora displays have been observed and are still possible to be seen from Scotland, Norway, large parts of Sweden, Finland and even Estonia. The images below were taken just a few hours ago by SpaceWeatherLive teammember Marcel from Luleå, Sweden.
