An X-class solar flare (R3-moderate) has just peaked! The maximum measured X-ray flux was X1.59 to be precise and the solar flare peaked at 14:29 UTC. Sunspot region 2838 is the source of this eruption. The solar flare seems fairly impulsive and due to the location of the sunspot region, any ejecta is unlikely to be earth-directed.
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.
