Note: The source of this CME is an eruption from active region 12862 located near the SW limb of the Earth-facing disk. The eruption is best seen in SDO/AIA 171, 193, and 211 starting around 2021-08-28T12:30Z as opening field lines followed by a post-eruptive arcade starting around 2021-08-28T14:00Z. The CME appears fast with a bright bulk of the CME directed SW with a more faint portion more equatorward.

CME Analysis M2M_CATALOG LE RHB BW SH true SWPC_CAT 72.0 -12.0 777.0 C 29.0 2021-08-28T17:46Z This CME was difficult to measure in difference imagery due to a bright shock front that was slightly faster than the bulk of the CME. Speeds ranged from 650-800km/s depending on the feature tracked in swpc_cat. StereoCAT measurements yielded similar results. The width of this CME is wider than the more bright portion of the CME due to the portion that is more equatorward adding width to the CME. 1: Result 1 (2.0 AU)
