All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-05-20T14:48:00-CME-001 (version 1)
Note Keyword:
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: CME observed to the west in SOHO LASCO C2/C3 and GOES CCOR-1, and additionally to the west for 3 frames of STEREO A COR2 after a data gap from 2025-05-20T12:38Z-16:38Z; data gap resuming at 2025-05-20T17:09Z. The source is likely an opening of field lines visible beyond the western limb in SDO AIA and GOES SUVI 171 imagery starting around 2025-05-20T14:00Z/
