Note: Very faint CME first seen to the S in SOHO LASCO C2 starting around 2026-05-06T22:00Z. It is also seen to the S in SOHO LASCO C3 and GOES CCOR-1 but is covered by a real-time data gap in STEREO A COR2. There are two source candidates for this CME. The first is an eruption from AR 14431 beginning around 2026-05-06T16:20Z best seen in SDO AIA 304. The second and more likely source candidate is a filament eruption beginning around 2026-05-06T19:00Z. The filament spans approximately S30-40E00-30 and is best seen lifting off in SDO AIA 304.

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 |

Very approximate measurement based on the location of the likely associated filament eruption. There is a high degree of uncertainty in this measurement due to a lack of triangulation. Additionally, the leading edge is very faint and difficult to track. |
