CME Analysis Information (for CME activity ID: 2025-03-25T15:23:00-CME-001)
Catalog: M2M_CATALOG
Data Level: 0 (0=real-time, 1=real-time and checked by supervising forecaster, 2=retrospective science level data analysis)

Note: 
Measurement made using the source location seen in UV imagery of the Earth-facing disk, three frames of STEREO A COR2 running difference imagery with timestamps 2025-03-25T15:23Z, 2025-03-25T15:38Z, and 2025-03-25T15:53Z, as well as one frame of SOHO LASCO C3 running difference imagery at timestamp 2025-03-25T17:54Z. The leading edge is extremely diffuse in SOHO LASCO C3, which introduces some uncertainty. The leading edge of the CME is more clearly defined in the three frames of STEREO A COR2 than in SOHO LASCO C3. | Analysis of this CME was affected by a data gap in SOHO LASCO C2 and C3 imagery lasting from 2025-03-25T13:42Z to 2025-03-25T17:30Z, reduced image quality of SOHO LASCO C3 frames for timestamps following 2025-03-25T17:30Z, and by the regular overnight data gap in STEREO A COR2 imagery which began at 2025-03-25T15:53Z.
