First X-class solar flare of Solar Cycle 25
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.
