Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-09-05T20:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2023-09-05T20:36:00-CME-001 (version 1)
Note Keyword:
3P: 3-part structure CME
COL: Possible collision with previous CME
HAL: Halo CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
FS: Flux Rope and Shock Candidate
Note: Halo CME seen mostly to the northwest in SOHO LASCO C2 and C3 during a STEREO A data gap. Associated with a far-sided eruption as evidenced by fast moving field lines seen in SDO 171 and SDO 193 around 20:24Z off the western limb, perhaps from the same source as CME: 2023-09-05T14:00Z.

If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type |

One spacecraft measurement assuming the source is associated with old AR 3413, potentially around longitude 125-130. A high half-width was required to achieve the shape of the leading edge and to obtain a similar longitude as was obtained for the CME: 2023-09-05T14:00Z event, though a far-sided longitude closer to 160 but a less excessive half-width is also a possible source. The lower longitude also fits observations better as we seen the front off the western limb. |

Measurement based on the potential source location of old Active Region 3413 which rotated off the Earth-facing disk on 2023-09-03. This measurement uses a narrower half-width which resulted higher longitude, however, only SOHO LASCO C2/C3 imagery is available for this event and the source location is approximate so the longitude may vary. |
