What a week we are having! Hello Solar Cycle 25! Sunspot region 2891 (which is directly facing Earth!) produced a very long duration M1.7 (R1-minor) solar flare this morning that peaked at 03:01 UTC.
A lot of people come to SpaceWeatherLive to follow the Solar activity or if there is a chance to see the aurora, but with more traffic comes higher costs to keep the servers online. If you like SpaceWeatherLive and want to support the project you can choose a subscription for an ad-free site or consider a donation. With your help we can keep SpaceWeatherLive online!
