Note Keyword:
3P: 3-part structure CME
FOV: Front Bright front; may be evidence of pileup
HAL: Halo CME

Morphology Keyword:
Note: Significant partial halo CME SW in STEREO A COR2 and full southern halo in SOHO LASCO C2/C3. Source: X1.0 class flare from AR 2887 at S26W4 peaking at 2021-10-28T15:35Z and the associated significant eruption (with an EUV wave) seen starting around 2021-10-28T15:25Z as a large ejecta East of the AR 2887 and as significant area dimming north of the AR in AIA 193/171, also seen in EUVI A 195 as an EUV wave, dimming and ejecta (east of the AR). No clear shock front feature was seen, although there are protruding "tentacles" in front of the more solid front of the CME seen especially in C3.

Initial analysis with 6 early frames (including 1 starting frame in SOHO LASCO C3). The longitude of 0 deg. is based mostly on the appearance of CME as a symmetrical (southern) halo in SOHO LASCO C2. The fitting in SWPC CAT indicated higher latitude than the lat of the source (AR 2887 at S26W04) and of associated flare. Fitting suggested a higher half-width than the default 45 deg. and 49 deg produced a decent fit. |
