Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-06-23T00:39Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2023-06-23T00:39:00-CME-001 (version 1)
Source Location: S20E40
Active Region Number: 13341
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
LS: Loop and Shock Candidate
Note: Large mostly faint CME visible to the SE in STEREO A COR2 and after a data gap in SOHO LASCO C2 and C3. The source is an M4.8 class flare from AR13341 (S15E40) with southward deflection from the source. The flare is associated with brightening from a region to the south of the active region seen best in SDO/AIA 304 starting around 2023-06-22T23:40Z with dimming around the same time seen in SDO/AIA 193, 171, and 211. Additionally, there is an EUV wave and moving/opening field lines visible to the SE in SDO/AIA 193, 171, and 211.

CME Analysis M2M_CATALOG LE SH true SWPC_CAT -41.0 -43.0 665.0 C 35.0 2023-06-23T05:24Z Faintness of front and upper boundary made for difficult analysis. StereoCAT measurements were also conducted with speeds ranging between 600-800 km/s using single-spacecraft mode and adjusting for source location. The degree of uncertainty with these parameters is fairly high due to faintness of event. 1: Result 1 (2.0 AU)
