  • Catalog: M2M_CATALOG
  • Start: Thu, 14 Mar 2024 10:03:00 +0000
  • Source:
  • Region:
  • Note: Very faint CME better seen in STEREO A COR2. This CME follows and partly overlaps with the 2024-03-14T09:23Z CME. No source for this CME has been found.

  • Catalog: M2M_CATALOG
  • Start: Thu, 14 Mar 2024 09:23:00 +0000
  • Source: N35W05
  • Region:
  • Note: Source of this high northern latitude CME is an eruption of a large filament seen after 2024-03-14T08:00Z. The erupting filament stretches from ~N50E15 to N30W15. The eruption is best seen in EUV STEREO A 304/195 and SDO AIA 304/171/193. There is a dimming area (mostly stretching towards the north) and post-eruptive arcades centered around ~(N35W05).

  • Catalog: M2M_CATALOG
  • Start: Thu, 14 Mar 2024 05:08:00 +0000
  • Source:
  • Region:
  • Note: Faint CME with dimpled front and an even fainter wider shock. Its source is a prominence eruption from behind the limb, with a relatively narrow ejecta seen in SUVI 304/AIA 304/171/193 at 2024-03-14T07:24Z. Former Active Region 13590 is now at the longitude of about -115 deg and could be a possible source of this CME.

  • Catalog: M2M_CATALOG
  • Start: Wed, 13 Mar 2024 09:04:00 +0000
  • Source:
  • Region:
  • Note: This CME is visible to the north in SOHO LASCO C2/C3 and STEREO A COR2 coronagraph imagery. The source is likely far-sided as there are no source signatures visible on the Earth-facing disk.

2024-03-12T21:08:00-CME-001

  • Catalog: M2M_CATALOG
  • Start: Tue, 12 Mar 2024 21:08:00 +0000
  • Source:
  • Region:
  • Note: This CME is visible to the east in SOHO LASCO C2/C3 but is not visible in STEREO A COR2 imagery due to a data gap from 2024-03-12T19:53Z to 2024-02-13T03:09Z. The source is likely an eruption on or near the eastern limb seen in SDO AIA 131, 171, and 193 imagery starting around 2024-03-12T20:00Z.

2024-03-12T10:55:00-CME-001

  • Catalog: M2M_CATALOG
  • Start: Tue, 12 Mar 2024 10:55:00 +0000
  • Source: S19E90
  • Region:
  • Note: Faint CME seen to the SE in all coronagraphs. Source is a C3.3 class flare which peaked at 2024-03-12T10:18Z from on SE limb, around S19E90 but may be just inside or just beyond the limb, best observed in SDO AIA 131. An associated filament eruption and opening of field lines is observed in SDO AIA 171/193/211/304 at this time.
