Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-06T17:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-04-06T17:36:00-CME-001 (version 2)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
Morphology Keyword:
O: Other
Note: Faint and narrow CME visible to the NE in SOHO LASCO C2/C3 imagery. There is no clear source apart from some subtle and slow field line movement visible on the NE limb in SDO AIA 171 around 2025-04-06T16:15Z. The leading edge becomes diffuse partway through the SOHO LASCO C3 field of view. There was no STEREO A COR2 imagery available in real time for this CME due to a data gap which lasted from 2025-04-06T10:53Z to 2025-04-06T17:23Z.

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

The leading edge becomes diffuse partway through the SOHO LASCO C3 field of view. There was no STEREO A COR2 imagery available in real time for this CME due to a data gap which lasted from 2025-04-06T10:53Z to 2025-04-06T17:23Z. Not modeled Hannah Hermann on 2025-04-07T00:20Z
