Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-01-03T12:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-01-03T12:12:00-CME-001 (version 1)
Source Location: N10E64
Active Region Number: 13947
Note Keyword:
GAP: Data gap
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: Wide loop CME first seen in the NE by SOHO LASCO C2 beginning at 2025-01-03T12:12Z, as well as by SOHO LASCO C3 in later frames. This CME is not visible in STEREO A COR2 imagery due to a data gap beginning at 2025-01-03T11:09Z. The source of this CME is an X1.2 flare from AR 3947 (N10E64) peaking at 2025-01-03T11:39Z. This flare is seen clearly in GOES SUVI 94 and 131 imagery, along with field line movement visible in GOES SUVI 171, 195 and 284.
