Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-12-08T16:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-12-08T16:24:00-CME-001 (version 1)
Note Keyword:
HAL: Halo CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: This CME is observed as a far-sided partial halo to the NW in SOHO LASCO C2/C3 and STEREO A COR2 coronagraph imagery. The source is likely far-sided, with faint field line movement visible beyond the NW limb starting around 2023-12-08T16:10Z as seen in SDO AIA 171 imagery.

Prime?"primary flag" which is either True or False. 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 |

Measurement of the inner bulk portion based on the best fit between SOHO LASCO C3 and STEREO A COR2 imagery. Multiple measurements produced speeds ranging from about 550 to 650 km/s. Since this event is far-sided and a precise source location is unknown, the measured parameters may vary slightly. |

Measurement of the brighter shock portion visible to the northwest. There is a fainter portion of the shock feature which appears to form almost a full halo, but it is diffuse and difficult to measure. Multiple shock measurements produced speeds ranging from 747 km/s to 999 km/s. |
