Note: The source of this CME is an eruption seen in SDO/AIA 193 starting at 2021-05-13T15:42Z from Active Region 12822. The eruption appears to deflect northward and features a broad dimming region north of the active region. A post-eruption arcade field line movements are visible in SDO/AIA 193 and 171. This eruption has two B-class flares occur during it (one B1.1 class flare peaking at 2021-05-13T16:21Z and one B1.2 class flare peaking at 2021-05-13T18:15Z). The resulting CME is best seen to the West in STEREO-A COR2 imagery. It appears as a faint partial-halo to the North of SOHO/LASCO C2 and C3 coronagraphs.

CME Analysis M2M_CATALOG BW SH true SWPC_CAT -8.0 10.0 475.0 S 27.0 2021-05-14T02:43Z Due to the faintness and a slight dimpled front from SOHO's point-of-view, this CME was measured using the shock front seen in SOHO/LASCO C2 and STEREO-A COR2 imagery. When measuring using the black/white boundary, speeds were closer to 350-400km/s. 1: Result 1 (2.0 AU)
