Source Location: N18W11
Active Region Number: 13744
Note Keyword:
Faint: Faint event; may affect type assignment
HAL: Halo CME

EUVW: EUV Wave
Morphology Keyword:
Note: Faint CME seen as a halo in SOHO LASCO C2/C3 and a partial halo in STEREO A COR2. The source is an M1.9 flare from AR 3744 (approx. N18W11) with peak time 2024-07-16T22:06Z. EUV wave, opening field lines, and dimming are best seen in SDO AIA 171/193. The eruption is not visible in STEREO A EUV imagery due to a data gap from 2024-07-16T13:35Z to 23:35Z. While there is some field line opening associated with another M-class flare shortly beforehand, M1.6 with peak time 2024-07-16T21:24Z, the broad area of dimming is more clearly associated with this later M1.9 flare.

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 |

Preliminary measurement based on faint halo feature of CME, which may possibly be the shock. The CME may deflect from the source location. |
