CME Analysis M2M_CATALOG true SWPC_CAT 12.0 -21.0 1383.0 O 41.0 2020-12-07T18:49Z This is an updated measurement that uses a negative latitude more consistent with the location of the CME's source signature from AR2790. SOHO LASCO data was still unavailable when this measurement was made. 1: Result 1 (2.0 AU)
Earth = 2020-12-09T05:23Z (PE: -20.1 h)

CME Analysis M2M_CATALOG false SWPC_CAT 12.0 -10.0 1560.0 O 52.0 2020-12-07T18:34Z This is a preliminary measurement made with SWPC_CAT using only STEREO A COR2 difference imagery since SOHO LASCO data is unavailable during real-time analysis. The chosen longitude is based on the corresponding eruption signature visible in SDO AIA 193/304. 1: Result 1 (2.0 AU)
Earth = 2020-12-09T00:03Z (PE: -25.4 h)
