2025-02-02T12:38:00-CME-001

  • Catalog: M2M_CATALOG
  • Start: Sun, 02 Feb 2025 12:38:00 +0000
  • Source:
  • Region:
  • Note: This event is visible to the west/northwest in STEREO A COR2, but is it not observed in SOHO LASCO C2/C3 imagery. The source is likely far-sided as there are no corresponding signatures on the Earth-facing disk around the time of this event. There is an eruption visible beyond the southwest limb in STEREO A EUVI 304 imagery starting around 2025-02-02T10:15Z and again around 13:15Z, but both of these eruptions appear too far south to be associated with this event.

  • Catalog: M2M_CATALOG
  • Start: Sun, 02 Feb 2025 05:48:00 +0000
  • Source:
  • Region:
  • Note: This CME is visible as a far-sided halo directed towards the south/southwest in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is likely far-sided, with a fast opening of field lines visible over the southwest limb in SDO AIA 171, 193 and GOES SUVI 284 imagery starting around 2025-02-02T05:38Z. Eruptive material is also visible over/beyond the southwest limb starting around 2025-02-02T06:00Z as seen in SDO AIA 304 and GOES SUVI 304 imagery. It is possible this event is associated with former Active Region 13961, which was located approximately around longitude 170-175 degrees at the time of this event.

  • Catalog: M2M_CATALOG
  • Start: Sat, 01 Feb 2025 17:24:00 +0000
  • Source:
  • Region:
  • Note: Minor, faint loop appearing to the west-northwest in SOHO LASCO imagery following behind the outflow of CME: 2025-02-01T14:24Z to the west. Likely associated with a far-sided eruption as evidenced by moving field lines seen off the northwest limb best in GOES 284.

  • Catalog: M2M_CATALOG
  • Start: Sat, 01 Feb 2025 14:24:00 +0000
  • Source: S10W55
  • Region: 13979
  • Note: Narrow eruption seen to the west in SOHO/STEREO A associated with a minor eruption near the vicinity of Active Region 13979 near S10W55, exhibiting some westward deflection seen in GOES 284/304 and SDO 193/171/304.

  • Catalog: M2M_CATALOG
  • Start: Fri, 31 Jan 2025 14:38:00 +0000
  • Source: N14E43
  • Region: 13978
  • Note: This CME is visible to the W/NW. The source is an M6.7 flare from AR13978 (N14E43), based on SDO/AIA 131 imagery, peaking at 2025-01-31T14:06Z. Associated filament ejecta is visible in SDO/AIA 304 starting around 2025-01-31T13:51Z. Moving/opening field lines and EUV wave are also visible along the NW limb in GOES SUVI 284 starting around 2025-01-31T14:00Z.

  • Catalog: M2M_CATALOG
  • Start: Thu, 30 Jan 2025 18:12:00 +0000
  • Source:
  • Region:
  • Note: Loop CME seen to the West in SOHO LASCO C2/C3. This CME is not captured by STEREO A COR2 due to a data gap which started at 2025-01-30T15:09Z. The source of thus event is field line opening seen along/from just beyond the Western limb starting at 2025-01-30T17:57Z in SDO AIA 171, 193 and GOES SUVI 284.
