X9.0 solar flare! Strongest flare of Solar Cycle 25!
Sunspot region 3842 is on fire! This region is in a perfect earth-facing position and today produced the strongest solar flare of the current solar cycle! It was an X9.05 solar flare (R3-strong) that peaked at 12:18 UTC. This is in fact the strongest solar flare in 7 years. The last time we had solar flares bigger than this one was back in 2017! Yes that is the previous Solar Cycle!
