Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-02-16T14:08Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2

Activity ID: 2026-02-16T14:08:00-CME-001 (version 2)
Note Keyword:
GAP: Data gap
HAL: Halo CME
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME

FIL: Filament eruption
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
Note: CME first seen to the E in STEREO A COR2 starting at 2026-02-16T14:08Z. This CME is also visible as a very faint partial halo in SOHO LASCO C2 following earlier, faster CME: 2026-02-16T13:23Z. The source of this CME is possibly related to the same eruption that resulted in CME: 2026-02-16T13:23Z. The main eruption is best seen in SDO AIA 171 and SDO AIA 304 starting around 2026-02-16T12:18Z spanning S30E15 to S10W05. There are a couple of smaller portions of the eruption that could be responsible for this CME. The first is an area of dimming that is deflected slightly to the north best seen in SDO AIA 193. The second is an area of dimming south of AR 14373 that follows the main eruption. It is also best seen in SDO AIA 193. In real time, the original analysis of this CME was complicated by gaps in the SOHO and STEREO A downlink schedules.

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 |
