All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
Activity ID: 2022-12-30T16:53:00-CME-001 (version 2)
Source Location: N18E08
Active Region Number: 13076
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
FLR: Flare
BR: Brightening
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
F: Flux Rope
Note: CME seen to the SW in STEREO Ahead along the SW streamer during a SOHO data gap. Likely associated with ejecta following an M1.4-class flare from AR13176. Distinct EUV wave visible in GOES SUVI 195 starting around 2022-12-30T15:28Z to the S/SW of the eruption and continues to spread with some deflection to the South, likely due to a nearby coronal hole. There is also some EUV wave and dimming seen to the SW of the eruption that may have been caused by an earlier eruption starting around 2022-12-30T11:30Z that may have caused an additional front and potential separate CME feature to appear in the white-light imagery just ahead of the wider measurable portion of this CME. The two CMEs are treated together here due to this being heavy speculation with no SOHO imagery to confirm suspicions.

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 |

Remeasured using more available imagery in SWPC_CAT, primarily using STEREO A COR2 and including one frame of SOHO LASCO C3. CME speed appears to decrease as it moves further out in the coronagraphs. |

Very early preliminary leading edge measurement using just a few frames of STEREO Ahead with an assumption of the source location. SOHO C2/C3 data was unavailable at the time due to a data gap. |

Very preliminary measurement using three later frames in STEREO A COR2 imagery tracking the wider portion of the CME. Updated measurements are likely still to come. No available SOHO imagery during this measurement. |
