M1.1 solar flare, coronal hole facing Earth
Newly numbered sunspot region 2321 looks to have fully rotated into view and was the source of an M1.1 (R1-minor) solar flare at 09:50 UTC. SOHO coronagraph imagery show that a minor coronal mass ejection was launched but it will more than likely be directed away from Earth.
