Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-08-02T01:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-08-02T01:36:00-CME-001 (version 1)
Source Location: N20E50
Active Region Number: 13775
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
OVR: Event partially overlaps with another CME
Source Signature Keyword:
PEA: Post eruption arcade
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: Faint CME seen to the NNE in all coronagraphs, though becomes quite faint in SOHO LASCO C3/ later frames of STEREO COR2A. The likely source for this CME is a sputtering eruption from AR 3775 beginning around 2024-08-02T00:42Z, seen as field line movement and some material flowing out along field lines in SDO AIA 171, but not in a crisp clean eruptive motion. More evidence for this source comes from a broad post-eruptive arcade over the region forming around 2024-08-02T02:24Z.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type.

CME Analysis M2M_CATALOG LE true SWPC_CAT -50.0 47.0 329.0 S 30.0 2024-08-02T12:30Z Triangulated measurement between SOHO LASCO C2/C3 and STEREO COR2A using AR 3775 as a source, finding a good fit deflected northward. This front is very faint and diffuses late in C2 and COR2A frames, and is barely visible in C3, so some uncertainly lies in tracking the true front as it fizzles.
