Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-01-20T23:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-01-20T23:12:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
OVR: Event partially overlaps with another CME
Source Signature Keyword:
Morphology Keyword:
LS: Loop and Shock Candidate
Note: Very faint CME to the E/SE in SOHO LASCO C2 and C3 imagery. Not visible in STEREO A imagery due to data gap. This CME is quickly overtaken by the CME first seen in SOHO LASCO C2 at 2024-01-21T00:36Z. There is no clear source for this CME, but it appears to have a potential faint shock ahead of a main "bulk" portion. Both features are very faint and difficult to see in white-light imagery (easier to see in motion in SOHO LASCO C3 imagery).

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. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type
