OFL: Moving/Opening field lines
Morphology Keyword:
Note: Narrow, fast CME to the SW in STEREO A COR2 and GOES CCOR-1. There is currently a data gap in SOHO LASCO C2 and C3 imagery. The source is seen as moving/opening field lines starting around 2025-05-01T08:39Z to the SW in SDO/AIA 193 and 171. An associated small filament eruption is also visible in SDO/AIA 304 and STEREO A EUVI 304 to the SW. This eruption is likely associated with old AR 14065 which rotated off the Earth-facing disk late on 2025-04-29. The estimated longitudes of the source are (~S31W110 to ~S31W125) based on calculation of average rotation and visible inspection of STEREO A EUV imagery. This active region is situated within a coronal hole which may attribute to deflection.
