AR11532 has a magnetic delta structure in the largest leading penumbra and many spots spread out over a large area. Further M class flaring is possible. Flare: M6.1/2N at 20:56 UTC. A partial halo CME was observed after this event, the CME could have a minor Earth directed component. NOAA forecasters estimate a 25% chance of additional M-flares during the next 24 hours, although the actual odds seem higher.
