M2.1 solar flare, glancing blow shock passage possible

Sunspot region 2415 produced an M2.1 solar flare (R1-minor) that peaked yesterday at 18:03 UTC. This solar flare was a long duration event and early imagery from SDO suggested right away that this solar flare was associated with a coronal wave and coronal dimming. Fancy words... yes we know... but these two solar features are classic signs that the solar flare launched a coronal mass ejection.
