Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-26T21:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-10-26T21:12:00-CME-001 (version 1)
Note Keyword:
HAL: Halo CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
Morphology Keyword:
L: Loop
Note: Partial halo half-loop to the NE in SOHO LASCO C2/C3 and GOES CCOR-1, overlapping with the 2025-10-26T20:36Z northern brighter halo CME. Fully covered by a large daily data gap in STEREO A. Its source was not found, so is likely far-sided. The former AR 4246 should be at -165 deg long at the time, however the latitude of this CME is lower than the 24 degrees of this AR.

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
