Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-02-02T13:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-02-02T13:36:00-CME-001 (version 3)
Note Keyword:
3P: 3-part structure CME
COL: Possible collision with previous CME
HAL: Halo CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Very fast CME consisting of a narrow BULK portion seen to the East in SOHO LASCO C2/C3 and STEREO A COR2, and a full halo SHOCK portion seen emerging shortly after the bulk. The only source signature in UV imagery is widely and rapidly opening field lines originating from beyond the southeast limb, seen around 2024-02-02T13:32Z in SDO AIA 171/193 and GOES SUVI 284. The candidate source location may possibly be old Active Region 13550, which is estimated to be located at approximately S16E120 based on visual inspection of the NSO GONG Farside Map.

CME Analysis M2M_CATALOG LE true SWPC_CAT -124.0 -10.0 1815.0 O 32.0 2024-02-02T15:25Z Measurement of the BULK based on source location in UV imagery and best fit between coronagraphs, especially using later frames of SOHO LASCO C3 difference imagery (see clear loop in C3 difference frame: 2024-02-02T14:42Z). Temporary broadening of cadence in STEREO A COR2 imagery caused leading edge to be very faint in running difference imagery. 1: Result 1 (2.0 AU)
Parker Solar Probe = 2024-02-04T00:00Z
2: Result 2 (5.5 AU)
Parker Solar Probe = 2024-02-04T00:00Z

CME Analysis M2M_CATALOG SH true SWPC_CAT -146.0 -6.0 615.0 C 66.0 2024-02-02T19:45Z Measurement of an interesting feature that emerges following the leading edge of the bulk. Feature appears visually to be wide, faint, and shock-like, however the speed is significantly slower than the bulk measurement, which adds high levels of uncertainty to the true nature of this feature.
