Sunspot region 3663 celebrates the start of a new week with a massive X4.5 (R3-strong) solar flare. This is the third strongest solar flare of solar cycle 25 and the strongest solar flare produced by this sunspot region thus far. Sounds great right? When will I be able to see aurora I hear you ask...
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!
