Note: Very faint and narrow CME seen to the SW in SOHO LASCO C2/C3. Source is likely a small flare and narrow ejecta from S17W34 (near AR 3638) at 2024-04-21T10:51Z as seen in SDO AIA 304, at 10:49Z in GOES SUVI 304. Small patch of brightening seen at source location in STEREO A EUVI 195 at 10:55Z; lingering narrow ejecta material seen in STEREO A EUVI 304 at 11:15Z. Data gap in STEREO A COR2 lasting from 2024-04-21T11:38Z to 2024-04-22T02:23Z (with one frame timestamped 2024-04-2119:23Z). No STEREO A COR2 imagery was available for this CME.
