We talked yesterday about how close together sunspot regions 2172 and 2173 are and that they might interact with each other. Well, they did not disappoint! Both sunspot regions worked together to produce an M5.1 solar flare (R2-moderate radio blackout) that peaked at 02:58 UTC on 28 September.
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.
