Note: This CME is visible to the west/southwest in SOHO LASCO C2/C3 imagery and STEREO A COR2 imagery following a data gap which lasts until 2024-01-28T01:53Z. The source is likely an eruption from just beyond the western limb starting around 2024-01-27T21:00Z as seen in SDO AIA 131, 171, 193, 304 imagery. Opening field lines can be observed at this time near the western limb in SDO AIA 171 and 193 imagery.

CME Analysis M2M_CATALOG LE true SWPC_CAT 97.0 -29.0 321.0 S 28.0 2024-01-28T08:23Z Measurement based on the best fit between SOHO LASCO C3 and STEREO A COR2 coronagraph imagery. The measured longitude may vary as the precise source location is unknown. Multiple measurements produced longitudes ranging from 90 to 120 degrees. 1: Result 1 (2.0 AU)
