Activity ID: 2024-03-17T03:12:00-CME-001 (version 1)
Source Location: S35W20
Note Keyword:

OVR: Event partially overlaps with another CME
Source Signature Keyword:
PEA: Post eruption arcade
FIL: Filament eruption
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
Note: This CME is visible as a partial halo directed towards the southwest in SOHO LASCO C2/C3 and STEREO A COR2 coronagraph imagery. The source is a filament eruption spanning S45E05 to S15W40 seen in SDO AIA 131, 171, 193, and 304 imagery starting around 2024-03-17T02:30Z. Dimming is visible from the eruption site shortly after the filament lifts-off, starting around 02:37Z, seen in SDO AIA 193 and field line movement can be seen near the S/SW limb at this time in SDO AIA 171. Post-eruptive loops begin to form around 04:30Z as seen in SDO AIA 171 and 193 imagery. This event partially overlaps CME: 2024-03-17T03:36Z, which also likely occurs from the same filament eruption.

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 faint shock feature, which is only visible for a few early frames in SOHO LASCO C2 and STEREO A COR2 imagery, based on the approximate source location and best fit between coronagraphs. |

Measurement of the bulk portion based on the approximate source location and best fit between SOHO LASCO C2/C3 and STEREO A COR2 imagery. Due to the irregular front of the CME, it was difficult to perfectly align the leading edge between coronagraphs. Multiple measurements resulted in latitudes ranging from -25 to -35 degrees, with consistent speeds around ~325 km/s. |
