Source Location: S26E90

EUVW: EUV Wave

Note: This CME is visible in SOHO LASCO C2 and C3 imagery to the S/SE in the outflow of the previous CME starting at 2025-03-01T18:24Z. It is not visible in STEREO A COR2 imagery due to a data gap beginning at 2025-03-01T21:38Z. The source of this CME is a partially occulted C9.5 flare from a region just beyond the SE limb near S26E90+ as seen in SDO/AIA and GOES SUVI 131 imagery. A well defined loop with filament ejecta in the middle is seen lifting from the source region with clear moving/opening field lines and EUV wave to the south starting around 2025-03-01T23:00Z. There appears to be strong deflection to the south with this event as evident by the moving/opening field lines in GOES SUVI 284 imagery.

Very preliminary measurement with limited frames in SOHO LASCO C2 and C3 imagery. No STEREO A COR2 available due to data gap. The CME exhibits a sheered-type of front with a portion moving faster than other portions. These parameters are based on following the faster portion of the CME with including the slower portion within the width of the measurement. The slower portion of this CME was measuring speeds closer to 200 km/s. |
