A complex eruption took place today which peaked at 01:33 UTC. The associated solar flare reached a peak of X1.1 (R3-strong) and came from sunspot region 3614. An unremarkable sunspot region north of sunspot region 3615. We say that the eruption is complicated because sunspot region 3615 flared at the same time but everything points to the solar flare and resulting eruption from sunspot region 3614 being stronger.
