What a way to sign off! Sunspot region 3664 (R3-strong) is now on the west limb and waves goodbye by producing the largest solar flare of Solar Cycle 25 which peaked at X8.7! Wow! There isn't any coronagraph imagery available from SOHO yet, but we do know the solar flare was eruptive but based on coronagraph imagery from STEREO A, the resulting coronal mass ejection is likely not aimed at Earth.
A lot of people come to SpaceWeatherLive to follow the Sun's activity or if there is aurora to be seen, but with more traffic comes higher server costs. Consider a donation if you enjoy SpaceWeatherLive so we can keep the website online!
