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.

Today's X-class solar flare is the first X-class solar flare of Solar Cycle 25 and the first X-class solar flare since the massive X8.2 solar flare that took place on 2017/09/10. Yes, it has indeed been almost 4 years since we last breached the X-class threshold. Isn't it crazy? Our Sun is one day early with her fireworks display to celebrate Independence Day with our American friends but we will take it nonetheless!

This morning we already got an M2.7 solar flare from sunspot region 2838. This solar flare peaked at 07:17 UTC and who would have guessed that this was a sign of things to come! A shame that this newly developed region is already on the north-west limb. It will transit onto the far-side of the solar disk in the next 24 to 48 hours and any future eruptions coming from it are for sure not going to be directed towards our planet.
