  • Catalog: M2M_CATALOG
  • Start: Wed, 12 Mar 2025 20:04:00 +0000
  • Source:
  • Region:
  • Note: CME first seen to the NE in SOHO LASCO C2 white light imagery starting at 2025-03-12T20:04Z. Also seen to the NE in SOHO LASCO C3 but is not seen in STEREO A COR2. This jet may have been visible in running difference imagery shortly before it was visible in white light imagery and has a half-width of less than ten degrees. There is not a good source candidate on the Earth-facing disk; however, there are some possible post eruptive arcades on or just beyond the NE limb (approximately N35-N40) best seen in SDO AIA 171 beginning around 2025-03-12T21:15Z that could be related to this jet.

  • Catalog: M2M_CATALOG
  • Start: Wed, 12 Mar 2025 11:12:00 +0000
  • Source:
  • Region:
  • Note: Super faint and narrow jet only seen in SOHO LASCO C2 running difference imagery and in a few early C3 images and not seen in STEREO A COR2. No source has been found for this jet.

  • Catalog: M2M_CATALOG
  • Start: Wed, 12 Mar 2025 07:12:00 +0000
  • Source:
  • Region:
  • Note: A super faint jet to the northwest, seen mostly in SOHO LASCO C2 and in a few early timestamps of C3 and too faint to be seen in STEREO A COR2. There is no flare that can be associated with it but there is some brightening in AR 14024 after 2025-03-12T06Z seen in SDO AIA 193 and it is possibly associated with activity in this Active Region.

  • Catalog: M2M_CATALOG
  • Start: Wed, 12 Mar 2025 07:00:00 +0000
  • Source:
  • Region:
  • Note: Bulbous jet-like CME to northeast (north in Stereo), similar to the 2025-03-11T23:24Z CME. No clear source was found on disk but there are some movements of field lines behind the limb in the NE after 05Z in AIA 193. The CME is likely farsided.

  • Catalog: M2M_CATALOG
  • Start: Tue, 11 Mar 2025 23:24:00 +0000
  • Source:
  • Region:
  • Note: Narrow, relatively fast CME seen to the northeast in SOHO LASCO C2 imagery and not seen in STEREO A COR2 due to a data gap; it appears similar in appearance to the CME: 2025-03-11T18:24Z which was determined to likely be far-sided. Few, if any sources on the Earth-facing disk suggest that this CME occurs with eruptive activity on the Earth-facing disk.

  • Catalog: M2M_CATALOG
  • Start: Tue, 11 Mar 2025 22:24:00 +0000
  • Source: N07W57
  • Region: 14024
  • Note: Narrow CME seen to the northwest in SOHO LASCO C2 during a COR2A data gap. Appears to be associated with a minor eruption from Active Region 14024 (N07W57) and C9.6-class flare as evidenced by dimming seen in SDO AIA 193 and GOES SUVI 294 starting around 2025-03-11T21:28Z as well as brightening visible in SDO AIA 131.
