Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-09T22:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2025-04-09T22:00:00-CME-001 (version 1)
Note Keyword:
GAP: Data gap
Source Signature Keyword:
Morphology Keyword:
J: Jet
Note: Faint and narrow jet CME visible to the W in SOHO LASCO C2/C3. No STEREO A COR2 imagery was available in real time for this CME due to a data gap which began at 2025-04-09T18:53Z. There was no clear source for this CME; there are several small instances of field line movement in the Western hemisphere of the disk and on the West limb, but none distinct enough to consider as a candidate source.

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 Plane-of-sky NONE 2.0 1136.0 O 10.0 2025-04-10T01:00Z Plane-of-sky measurement of the faint leading edge using several frames of SOHO LASCO C2 and two frames of SOHO LASCO C3. Unable to be tracked farther than two frames in SOHO LASCO C3, due to the C3 running difference imagery being heavily affected and/or corrupt beginning at timestamp 2025-04-09T22:40Z. No STEREO A COR2 imagery was available in real time for this CME due to a data gap which began at 2025-04-09T18:53Z. Not modeled Hannah Hermann on 2025-04-09T23:58Z
