Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-04-28T10:00Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

Activity ID: 2023-04-28T10:00:00-CME-001 (version 1)

Note Keyword:

FF: Event fails/disappears before exiting COR2

Morphology Keyword:

Note: This CME is faint but visible to the S/SE in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is uncertain, but there is field line movement visible beyond the southern limb seen in SDO AIA 171 around 2023-04-28T08:45Z. However, it was difficult to obtain a measurement with far-sided parameters. Nonetheless, there are no obvious source signatures on the Earth facing disk so it is still believed that this event is far-sided.

There are no obvious source signatures on the Earth-facing disk so it is believed that this event is far-sided. However, it was difficult to obtain a decent fit using far-sided longitudes.
