Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-12-18T11:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-12-18T11:12:00-CME-001 (version 1)
Active Region Number: 13920
Note Keyword:
GAP: Data gap
Source Signature Keyword:
BR: Brightening
Morphology Keyword:
Note: CME first visible to the NW in SOHO LASCO C2 starting at 2024-12-18T11:12Z. Also visible to the NW for a couple frames in SOHO LASCO C3 but is very faint. CME is mostly covered by a data gap in STEREO A COR2 from 2024-12-18T11:38Z to 2024-12-18T16:38Z. The source of this CME is most likely some minor brightening and general, continuous activity best seen in GOES SUVI 304 from AR 3920 in the NW for a few hours prior to and after the CME first emerges into SOHO LASCO C2, but there is no clearly definitive source candidate.
