Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-01-04T01:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-01-04T01:36:00-CME-001 (version 2)
Note Keyword:
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: Faint, hollow, and somewhat narrow CME seen to the NE in SOHO LASCO C2/C3 and STEREO A COR2. Overlaps with previous CME which was a farsided partial halo. Source is uncertain, but the best candidate is extremely faint field line movement which may indicate a rising loop seen in GOES SUVI 284 starting at 2024-01-04T00:36Z and centered at about N20.
There was also an eruption on the Earth-facing disk around this time. Brightening, ejecta, and post-eruptive arcades can be seen in UV imagery from AR 13536 (N05E37) around 2024-01-04T01:44Z with two associated M-class flares. However, the ejecta appears southward-deflected, while the CME seen in coronagraph imagery is directed to the north.

Updated measurement using a farsided source location, which achieves a better fit between SOHO LASCO C3 and STEREO A COR2 difference imagery. |

Used source location as starting point, with southern deflection. Some paralleling in fit line between C3 and COR2A. |
