Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-05-17T21:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-05-17T21:24:00-CME-001 (version 1)
Source Location: S11E65
Active Region Number: 13685
Note Keyword:
DPL: CME exhibits dimpled front
GAP: Data gap
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade

Note: This heart-shaped CME is seen to the E/SE in SOHO LASCO C2 and C3. This CME is not observed by STEREO A COR2 due to a data gap lasting from 2024-05-17T20:53Z to 2024-05-18T01:23Z. Associated with the M7.2 flare from AR 13685 (S13E52). Widely opening field lines, an EUV wave, and post-eruptive arcade can be seen in SDO AIA 171/193 starting at 2024-05-17T20:54Z, and ejecta and brightening can be seen in SDO AIA 304/171. This eruption is also visible in STEREO A EUVI 195 at 2024-0517T20:55Z as widely opening field lines and brightening, and in STEREO A EUVI 304 at 21:15Z as ejecta, brightening, and post-eruptive arcades.
