Incoming coronal mass ejection?
Sunspot region 2434 produced a long duration C4.4 solar flare that peaked today at 03:40 UTC. This solar flare was accompanied by a coronal mass ejection that is propagating mostly southwest of the Sun-Earth line. Sharp eyes can discover a very faint full halo outline if you watch the LASCO coronagraph imagery meaning an earth-directed component can not be excluded.
