Source Location: S23E37
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:

Morphology Keyword:
LS: Loop and Shock Candidate
Note: This CME is visible to the SE in SOHO LASCO C2, C3, and STEREO A COR2 imagery. The CME appears fairly faint in SOHO imagery, but is more clearly defined in STEREO A imagery. The source appears to be a minor/brief eruption from ~S23E37 starting around 2023-10-18T05:37Z with filament ejecta visible in SDO/AIA 304 starting around 06:00Z and associated dimming seen at 06:38Z following eruption in SDO/AIA 193. There are some minor and brief post-eruptive arcades visible in SDO/AIA 193 and 335 best seen around 06:30Z.

These parameters are based off of the best fit between SOHO LASCO C2 and STEREO A COR2 imagery. SOHO LASCO C3 was not used due to the pilon arm obscuring the CME front within this field of view. This is a measurement of the bulk of the CME which is much brighter on the upper right hand boundary than the left hand boundary. This core is also much brighter than the shock associated with this CME. |

These parameters are a shock measurement of this CME using SOHO LASCO C2, C3, and STEREO A COR2 imagery. This shock is wider and can be tracked in a few frames in SOHO LASCO C3 compared to the bulk. This shock is fairly faint in difference imagery, so some uncertainty in parameters may be present. |
