Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-03-26T15:49Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2025-03-26T15:49:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
L: Loop
Note: Faint loop CME seen to the SE in SOHO LASCO C2. This CME is not captured in available frames of SOHO LASCO C3 or STEREO A COR2, due to a data gap in SOHO LASCO which began at 2025-03-26T16:42Z and a data gap in STEREO A COR2 which began at 2025-03-26T13:23Z. The source is likely brightening seen at S20 and just beyond the East limb at approx. E100 to E110 in GOES SUVI 304 at 2025-03-26T15:01Z, as well as faint opening loops seen off the SE limb in GOES 284 at 2025-03-26T15:15Z.

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

CME Analysis M2M_CATALOG LE true SWPC_CAT -124.0 -43.0 644.0 C 16.0 2025-03-26T21:04Z Measurement using an approximation of the source location just beyond the southeast limb based on UV imagery of the Earth-facing disk and the same four frames of SOHO LASCO C2 used in the plane-of-sky measurement. There is a high degree of uncertainty with this measurement due to the lack of available imagery and the uncertainty of the exact source location. Not modeled Hannah Hermann on 2025-03-27T02:06Z
CME Analysis M2M_CATALOG LE false Plane-of-sky NONE -53.0 527.0 C 15.0 2025-03-26T22:19Z Plane-of-sky measurement using four frames of SOHO LASCO C2 imagery. This CME is not captured in available frames of SOHO LASCO C3 or STEREO A COR2, due to a data gap in SOHO LASCO which began at 2025-03-26T16:42Z and a data gap in STEREO A COR2 which began at 2025-03-26T13:23Z.
