Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-05-09T06:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-05-09T06:48:00-CME-001 (version 1)
Source Location: N15W24
Active Region Number: 13296
Note Keyword:
Faint: Faint event; may affect type assignment
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
FS: Flux Rope and Shock Candidate
U: Unknown
Note: This CME is visible to the W/NW in SOHO LASCO C2, C3, and STEREO A COR2 imagery. It is seen much brighter in STEREO A COR2 than in SOHO LASCO coronagraph imagery. The source appears to be from the M1.2 class flare peaking at 2023-05-09T06:13Z from AR13296. There is associated moving/opening field lines seen along the NW limb in SDO/AIA 171 following the flare as well as a minor EUV wave/dimming event that propagates to the SW best seen in SDO/AIA 211.
