GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: Faint CME front seen to the SW in SOHO LASCO C2 and C3. STEREO A COR2 has a data gap during the event from 2024-04-01T19:23Z to 2024-04-02T02:53Z. The source may possibly be moving/opening field lines from beyond the SW limb as seen in SDO/AIA 193 and 171 starting around 2024-04-01T19:00Z. These moving/opening field lines are also visible to the SW in STEREO A EUVI 195 just before the data gap. It's not clear exactly where these moving/opening field lines are sourced from, but it's possible they are from old AR13615 that rotated off the Earth-facing disk on 2024-03-30.

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.
