Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-06T21:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2025-04-06T21:24:00-CME-001 (version 1)
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 imagery. There is no clear source for this eruption, however, due to its similarity to earlier eruptive activity, it is possible that the source is associated with the ongoing minor field line movement and minor eruptive activity from beyond the E/NE limb. The leading edge becomes diffuse early in 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 began at 2025-04-06T20:53Z.

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 |

Plane-of-Sky measurement in swpc_cat taken using multiple frames of SOHO LASCO C2 running difference imagery. The leading edge becomes diffuse early in 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 began at 2025-04-06T20:53Z. |
