Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-09-05T14:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-09-05T14:36:00-CME-001 (version 1)
Note Keyword:
COL: Possible collision with previous CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: Faint loop CME seen to the SW in all coronagraphs, partially enveloped by the larger CME 2023-09-05T14:00Z that erupted shortly before. Source is likely over the SW limb, as the only notable signature at this time is opening field lines in SDO AIA 171 first observed around 2023-09-05T14:15Z. A potential source is old AR 3415 that rotated over the limb around 2023-09-04T13:00Z, putting it ~S09W100 for this CME timing, but this is not certain as we cannot directly observe this region.
