Note: This CME is visible to the northeast in STEREO A COR2 imagery, and is faint but may be seen to the northwest in SOHO LASCO C2/C3 and GOES CCOR-1 imagery. The source may be related to an eruption/brightening from Active Region 14493 (N10W05) starting around 2026-07-21T12:00Z seen in SDO AIA 131/171/193/304, GOES SUVI 131/171/195/284/304, and STEREO A EUVI 195/304 imagery. There is a coronal hole north and south of this eruption site which may account for deflection from the on-disk source location.

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 |

Speculative measurement based on the best fit between STEREO A COR2 and a faint leading edge seen in SOHO LASCO C2/C3 imagery. It is unclear if the feature visible in SOHO LASCO imagery is outflow or the same event that is seen clearly in STEREO A COR2 imagery. |
