Source Location: S21W12
Active Region Number: 13283
Note Keyword:
HAL: Halo CME
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
Note: This CME is a halo CME visible in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is a filament eruption starting around 2023-04-21T17:30Z visible in SDO AIA 131, 171, 193, 304, as well as STEREO A EUVI 195 and 304 imagery. An EUV wave is visible in SDO AIA 171 and 193 starting around 18:00Z, with an associated M1.7 flare peaking at 18:12Z. Post-eruptive dimming is visible in SDO AIA 193 starting around 18:15Z.

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 |

Shock front measurement assuming a larger half-width (>45 degrees) given the signature seen in SDO 193 and the relatively flattened shape the faint leading edge of the halo takes at its poles to the north and south. |
