Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-03-14T08:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-03-14T08:00:00-CME-001 (version 1)
Source Location: S20W12
Active Region Number: 13250
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
Morphology Keyword:
Note: CME first seen in SOHO LASCO C2 to the W/SW, as well as STEREO A COR2 to the W/SW. This is a faint event; it was difficult to identify a front to track. The suspected source for this CME is an eruption seen from AR13250 (S20W12). Post-eruptive brightening seen around 2023-03-14T05:57Z in SDO AIA 304 and opening field lines/dimming in SDO AIA 193. However, measurements of this CME (the bulk, at least) indicate significant westward deflection, which raises some uncertainty in this source location selection.

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 |

Measurement using best fit between coronagraphs. Front becomes diffuse halfway through STEREO A COR2 field of view. CME is barely emerging in three frames of SOHO LASCO C3. |
