Note: CME visible to the southeast in SOHO LASCO C2/C3 and in STEREO A COR2 along a streamer prior to a data gap starting at 2024-12-21T11:39Z. The start time is likely earlier, as part of this CME was visible in the coronagraphs as early as 2024-12-21T06:00Z, but did not start picking up speed and moving through the coronagraphs until around 2024-12-21T13:25Z. The source is unclear, and it is likely farsided.
