- Catalog: M2M_CATALOG
- Start: Fri, 21 Mar 2025 16:00:00 +0000
- Source: N02E07
- Region:
- Note: Faint halo CME with a bulk visible mainly to the SE in SOHO LASCO C2 and C3 imagery (more easily seen in difference imagery). There is no STEREO A COR2 imagery for this event due to a data gap. The source of this CME appears to be a large dimming region centered near N02E07 starting around 2025-03-21T15:49Z with a southeast directionality based on the minor EUV wave visible in SDO/AIA 211 and 193 imagery. There's a large coronal hole situated E/SE of the dimming region and a separate coronal hole due west of the dimming region which may have contributed to the deflection visible on the solar disk in SDO/AIA imagery. This source location appears to be a sympathetic eruption to the M1.2 flare from AR14028 (S17W33) seen to the SW in SDO/AIA 131 imagery.

- Region:
- Note: Faint CME seen to the SE in SOHO LASCO C2/C3, and to the S in two available frames of STEREO COR2A before a data gap begins at 2025-03-21T15:09Z. No source for this CME is observed in SDO and GOES imagery, suggesting a far-sided source alongside comparison between the CME direction in white light SOHO LASCO and STEREO COR2A imagery.

- Start: Thu, 20 Mar 2025 22:12:00 +0000
- Source: N08W75
- Region: 14022
- Note: Faint CME seen to the W in SOHO LASCO C2/C3 and STEREO COR2A. This CME is slow to evolve and appear as a defined front in the LASCO C2 field-of-view, and appears more clear in LASCO C3 and STEREO COR2A. The source for this CME is not observed as a distinct source, but appears to be continued outflow from CME 2025-03-20T17:12Z from AR 14022 centered at N08W75, corroborated via triangulation in the STEREO_CAT tool.

- Catalog: M2M_CATALOG
- Start: Thu, 20 Mar 2025 17:12:00 +0000
- Source: N08W75
- Region: 14022
- Note: Loop CME with brighter, narrower bulk and fainter shock visible to the west in SOHO LASCO C2/C3 during a STEREO A COR2 data gap. The source of the CME appears to the ejection of material from near the vicinity of Active Region 4022 just near N08W75, first distinctly seen as a distinct instance of opening field lines and brightening starting around 2025-03-20T17:24Z in SDO AIA 193 and 304 imagery. Faint flickering field lines far off the western limb seen in GOES SUVI 284 suggest that a component of this large scale eruption may be far-sided.

- Start: Wed, 19 Mar 2025 23:48:00 +0000
- Source: S07W100
- Region:
- Note: Faint loop CME visible to the northwest in SOHO LASCO C2/C3, with a faint flux rope feature more visible in STEREO A COR2 imagery. The source is the ejection of material from just beyond the southwest limb, first distinctly seen as a distinct instance of opening field lines and ejecta starting around 2025-03-19T23:15Z in GOES SUVI 304 and 284 imagery. Post-eruptive brightening extends onto the disk spanning from about S10 to S15 and W80 to W90, as seen in SDO AIA 304 at 2025-03-19T23:40Z. Associated surrounding field line movement extends into the northern hemisphere on or beyond the western limb, and some northern deflection occurs as the material erupts.

- Source:
- Region:
- Note: Faint but fast CME with an asymmetrical front, with a protruding nose to the south, seen directed to the west in SOHO with the start covered by the nighttime data gap in SOHO. Its source is the filament eruption seen on/behind the SW limb: as ejecta/prominence in AIA 304 (there are actually two ejectas - a more southern complex shaped loop-like prominence seen at 2025-03-19T22:50Z at latitude of -21, and a fan-shaped ejecta to the north of it seen at latitude of -7 at 2025-03-19T223:46Z. This eruption is also seen as fast opening of field lines behind the limb in AIA 193/171 starting at 2025-03-19T222:01Z and later (starting at 2025-03-19T223:21Z) as bright post-eruptive arcades on/behind the limb in AIA 131. There is an associated long duration occulted C6.0 flare peaking at 2025-03-20T00:07Z from behind the limb (bright arcades). It is possible that the flare is from former Active Region 4018 (S21W100).
