Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-17T00:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2026-07-17T00:12:00-CME-001 (version 1)
Note Keyword:
GAP: Data gap
Ha: Bright emission (likely H-alpha emission)
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
LS: Loop and Shock Candidate
Note: Bright loop CME first seen to the East by SOHO LASCO C2 beginning at 2026-07-17T00:12Z, as well as by SOHO LASCO C3 and STEREO A COR2 in later frames. This event is not seen in GOES CCOR-1 due to an outage which began at 2026-07-15T20:00Z. The source of this event is likely an eruption from beyond the East limb, evidenced by field line opening seen in SDO AIA 171, 193 and GOES SUVI 284 beginning at approx. 2026-07-17T23:30Z.

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 |
