Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-01-20T09:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-01-20T09:36:00-CME-001 (version 1)
Source Location: N15E90
Note Keyword:
COL: Possible collision with previous CME
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
OVR: Event partially overlaps with another CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: CME seen to the East in SOHO LASCO C2, C3 and STEREO A COR2. Lightbulb shape is discernable in white light imagery, but is extremely difficult to discern in difference imagery. Source is a prominence eruption on the NE limb, centered at about N17 and at E90. Rising loop and material seen in SDO AIA 171/193 starting at 2024-01-20T08:30Z. Movement of prominence material first seen in SDO AIA 304 at 2024-01-20T08:07Z after a data gap in SDO AIA imagery. Ejection of material seen in SDO AIA 304 at 2024-01-20T09:33Z. Some material seen falling back down to the solar surface around N20E80 in SDO AIA 304/171/193 at 2024-01-20T10:42Z.

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 tracking the leading edge, using source location on the East limb seen in UV imagery and best fit between coronagraphs. There is some uncertainty with this measurement, since this CME overlaps heavily with a previous filament eruption CME. |
