First M-class solar flare and geomagnetic storm of 2015
Solar activity increased to moderate levels thanks to an impulsive M1.1 (R1-minor) solar flare that peaked at 09:47 UTC from sunspot region 2253. There was no coronal mass ejection associated with this event. We are also under the influence of a coronal hole high speed stream and we even reached the G1 minor geomagnetic storm threshold in the early hours of 3 January according to the NOAA SWPC. Aurora were seen from many high latitude locations. Our header image was captured last night by Jüri Voit from Estonia. Stunning!
