CME Analysis M2M_CATALOG LE true Plane-of-sky NONE 13.0 356.0 S 13.0 2025-06-30T20:05Z A plane-of-sky measurement was made with STEREO A COR2 imagery using a longitude of -50 degrees due to the unknown source location. Additionally, this event is not visible in SOHO LASCO C2/C3 or GOES CCOR-1 imagery so a triangulated measurement was therefore unavailable. Not modeled Mattie Anastopulos on 2025-06-30T17:08Z
