Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-01-11T09:09Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-01-11T09:09:00-CME-001 (version 1)
Source Location: N24W80
Active Region Number: 13954
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
L: Loop
Note: Diffuse and relatively narrow CME to the N/NW first seen in STEREO A COR2 imagery, then shortly thereafter in SOHO LASCO C2/C3. Source is an eruption near the NW limb at N24W80 with narrowly opening field lines and ejecta seen starting at 2025-01-11T07:58Z in GOES SUVI 195/131/171/284 and a small rising loop of filamentary material seen in GOES SUVI 304 starting at 2025-01-11T07:57Z, all wavelengths showing heavy northern deflection. This eruption is associated with a C2.8 flare with peak time 2025-01-11T08:44Z produced by simultaneous brightening from recently-decayed AR 13954 (N24W76) as well as an unnumbered region just beyond the E limb located at an estimated N19E90-N19E100.

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 |

Measurement using source location and best fit between SOHO LASCO C3 and STEREO A COR2 difference imagery. Some uncertainty due to extreme faintness of leading edge in STEREO A COR2 difference imagery and use of reduced-cadence frames in C3 due to comet campaign. |
