M1.3 flare in the sun's east
While logging events in AR's in solar west and north, the GOES X-ray flux began to rise. At first the flare site could not be found - then the spotless eastern limb was viewed, showing this flare - which reached GOES M1.3, and was approaching its peak. Precursor events were missed.
The flare site is that of old AR11158 - site of the first SC24 GOES X2.2 Feb 15. The now spotless site hosted the strongest "spotless" flare that I've seen. It's assumed that a large filament ejected at the site - but searches in the H-alpha "wings" showed nothing. A strong CME from the site followed.
