Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-01-26T01:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-01-26T01:36:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
HAL: Halo CME
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: This is a partial halo CME visible to the SE in SOHO LASCO C2, C3 and more narrowly seen in STEREO-A COR2 to the E/SE. The source of this CME appears to be far-sided with moving/opening field lines visible in SDO/AIA 171 along the SE limb starting around 01:12Z. There is a data gap in STEREO-A during this event that prevents the ability to see the source eruption and the full progression of the CME in the STEREO-A COR2 field of view. This CME overlaps a more faint and narrow CME starting around 2023-01-25T21:12Z in SOHO LASCO C2.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type |

These parameters are based off of the best fit of the faint shock feature around the more narrow bulk. The shape of the shock could use a higher half-width to encompass more of the shock, but these parameters seemed to do the best job at matching the majority of the shape of the CME's shock. Measured speeds ranged between 800 km/s and 1100 km/s depending on the feature tracked (bulk on the lower end with shock on the higher end of speeds). Longitudes could vary by +/- 10 degrees due to limited STEREO-A COR2 imagery. |
