Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-25T03:24Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

Activity ID: 2025-04-25T03:24:00-CME-001 (version 1)

Note Keyword:

Faint: Faint event; may affect type assignment

FF: Event fails/disappears before exiting COR2

Source Signature Keyword:

Morphology Keyword:

J: Jet

Note: A super narrow faint jet to the east in both coronagraphs, better seen in running difference imagery. There was no source for it found in EUV imagery.

CME Analysis	M2M_CATALOG	LE	true	SWPC_CAT	-93.0	-9.0	671.0	C	10.0	2025-04-25T08:29Z	A very approximate analysis based on the fit with 2 coronagraphs (which can also be obtained with significantly different longitudes). No source has been found in EUV imagery to corroborate this measurement. The measurement is very approximate because of the narrowness of this jet (it is definitely <10 deg halfwidth), its faintness and the fuzziness of its front, as well as because of its availability only in a few overlapping timestamps in each coronagraph.	1: Result 1 (2.0 AU) OSIRIS-APEX = 2025-04-26T14:00Z	Anna Chulaki on 2025-04-25T18:23Z
