Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-12T00:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-04-12T00:48:00-CME-001 (version 2)
Source Location: N10W50
Note Keyword:
FOV: Front Bright front; may be evidence of pileup
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
Note: CME visible to the NW in SOHO LASCO C2/C3 and the north of STEREO A COR2. The potential source is activity from the vicinity of ARs 4055 (approx. N06W52) and 4058 (approx. N15W53) characterized by brightening best seen in SDO AIA 193 starting at 2025-04-11T23:13Z and opening/moving field lines best seen in SDO AIA 171/193. The eruption is not seen in STEREO A EUV imagery due to a data gap.

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.

CME Analysis M2M_CATALOG LE true SWPC_CAT 32.0 23.0 437.0 S 28.0 2025-04-12T11:36Z Measurement based on the best fit between SOHO LASCO C2/C3 and STEREO A COR2 imagery in SWPC_CAT as well as source location. The CME appears to speed up in later frames. The CME may deflect to the east of the potential source location. 1: Result 1 (2.0 AU)
