  • Catalog: M2M_CATALOG
  • Start: Mon, 16 Jan 2023 08:00:00 +0000
  • Source:
  • Region:
  • Note: This CME is visible to the SE in SOHO LASCO C2/C3 and STEREO A COR2 coronagraph imagery. The source is likely far-sided as there are no source signatures on the Earth facing disk.

  • Catalog: M2M_CATALOG
  • Start: Sun, 15 Jan 2023 05:00:00 +0000
  • Source: N13E56
  • Region: 13191
  • Note: This CME is visible to the NE in SOHO LASCO C2/C3 imagery. The source is likely an eruption and subsequent M6.0 flare from AR 3191 seen in SDO AIA 131, 171, 193 and 304 imagery. Since there's a data gap in COR2A at this time, it's hard to confirm if this CME originates from this source, but there are no other source signatures on the Earth-facing disk. Also, this event partially overlaps CME: 2023-01-15T03:48Z.

  • Start: Sun, 15 Jan 2023 03:48:00 +0000
  • Source: N13E56
  • Region: 13191
  • Note: This CME is visible to the E/SE in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is an eruption and subsequent M6.0 flare from AR 3191 seen in SDO AIA 131, 171, 193, 304 imagery starting around 2023-01-15T03:20Z. Opening of field lines is visible off the eastern limb in SDO AIA 171 at this time, and post-eruptive dimming appears around 03:45Z in SDO AIA 193.

  • Catalog: M2M_CATALOG
  • Start: Sat, 14 Jan 2023 21:36:00 +0000
  • Source: S16W44
  • Region: 13182
  • Note: This CME is visible as a partial halo to the W/SW in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is an eruption and subsequent M4.6 flare from AR 3182 seen in SDO AIA 131, 171, 193, 304 imagery starting around 2023-01-14T20:30Z. An opening of field lines is visible in SDO AIA 171 at 20:50Z and post eruptive loops start to form in SDO AIA 193 around 22:30Z. Eruption is also visible in STEREO A EUVI 195 and 304 imagery.
