STEREO A: SECCHI/COR2

Note: Small eruption on the Earth-facing disk after 2020-12-30T01:00Z, east of AR12795 near S20E08, as best seen by SDO/AIA 193/211 and STEREO-A EUVI 195 (towards the Western limb of the STEREO-A-facing disk). The shock front is possibly seen in COR2A after 2020-12-30T02:00Z, but it is very difficult to measure given the CME is faint and the apparent brightness of the western streamer.

If there are multiple CME analysis entries for a single CME, earlier measurements are marked as false when new or more accurate measurements are made. This is a helpful flag if you would like to download only one most accurate CME analysis per CME |

A CME-like shape can be seen in the difference imagery after 2020-12-30T02:00Z. I was only able to use the three images beginning at 2020-12-30T02:24Z to track in SWPC_CAT. |
