A major X7.1 solar flare (R3 radio blackout) peaked on 1 October at 22:20 UTC. The eruption took place around complex Beta-Gamma-Delta sunspot region 3842 close to the center of the earth-facing solar disk. This was in fact the second strongest solar flare of the current Solar Cycle thus far! An exciting jump in solar activity after a relatively quiet period with multiple potent sunspot regions currently on the solar disk!
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.
