Note: This CME is visible to the east in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery. The source is likely far-sided and may be related to faint field line movement visible beyond the eastern limb in GOES SUVI 284 imagery starting around 2025-07-21T13:00Z. It is possible this event exhibits eastern deflection due to a potential far-sided coronal hole as multiple measurements could not produce an accurate far-sided fit.

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 |

Measurement based on the best fit between SOHO LASCO C3, GOES CCOR-1, and STEREO A COR2 imagery. The measured longitude reflects eastern deflection from the far-sided source. Multiple measurements produced longitudes ranging from -70 to -63 degrees. |
