Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-03-07T22:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-03-07T22:12:00-CME-001 (version 1)
Source Location: S20W00
Active Region Number: 14012
Note Keyword:
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
F: Flux Rope
L: Loop
Note: This narrow on-disk CME is seen as a faint flux rope due south in SOHO LASCO C2 and simultaneously as a faint loop to the southeast in STEREO A COR2, which is currently 30 degrees to the west of SOHO LASCO. The source is a subtle eruption from AR 4012 (S20W00) starting at 2025-03-07T21:35Z, seen as dimming, brightening, and field line opening in SDO AIA 193 and 171, as well as GOES SUVI 284 and 304.

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 0.0 -25.0 1197.0 O 15.0 2025-03-08T00:28Z Best fit measurement using several frames of STEREO A COR2, four frames of SOHO LASCO C3, and two frames of SOHO LASCO C2. The leading edge is very faint in SOHO LASCO imagery; it is much more well-defined in STEREO A COR2. This CME visually overlaps with CME:2025-03-07T21:49Z in both SOHO LASCO and STEREO A COR2. 1: Result 1 (2.0 AU)
