Source Location: S28W58
Active Region Number: 12887
Note Keyword:
OVR: Event partially overlaps with another CME

FLR: Flare
PEA: Post eruption arcade
OFL: Moving/Opening field lines
EUVW: EUV Wave
Morphology Keyword:
Note: This CME is very brightly seen to the SW in SOHO LASCO C2/C3 and STEREO-A COR2. The source of this CME is a flare from Active Region 12887 (S28W58) with associated opening field lines seen in SDO/AIA 171 and 193 off of the southwest limb. This eruption is also visible in STEREO-A EUVI 195 toward the southwest limb starting around 2021-11-01T20:35Z.

This SWPC_CAT measurement matched leading-edge of the CME visible in STEREO A COR2 and SOHO LASCO C3. Based on the shape visible in SOHO LASCO C3 imagery, a westward deflection was analyzed with respect to where the eruption signature of the CME was observed (from AR 12887 near S28W59). |

These parameters are based on the best fit between the SOHO LASCO C2/C3 and STEREO-A coronagraphs. Out of the measurements made, longitudes for the best fit had a small range around 40 to 43 degrees. Half-width ranged from 45-50 degrees. Depending on the feature tracked, speed ranged from 675-830km/s. |
