Note: Extremely faint jet CME visible to the northwest in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. The leading edge is extremely diffuse. The source is associated with narrow field line opening seen on the NW limb around N35 which traces to either to a small area of post-eruptive brightening seen at N35W75 in SDO AIA 171 starting at about 2025-06-06T08:21Z or possibly to beyond the NW limb. Very subtle field line movement in the vicinity of N35W75 can also be seen in STEREO A EUVI 195, but there are several subtle instances of field line movement in the area of the disk, therefore it is difficult to identify an exact source.

Plane-of-sky measurement was using four frames of STEREO A COR2 imagery, before the leading edge becomes too diffuse to track. After several attempts, the leading edge of this CME is not reliably trackable in SOHO LASCO C3, C2, or in GOES CCOR-1; the leading edge is too diffuse or is not discernable in the imagery. The leading edge is visible and reliably trackable for a few frames in STEREO A COR2. |
