Note: This narrow, faint, jet-like CME is visible to the E/SE in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery. There are two potential sources for this CME which may indicated overlapping CME features of two separate CMEs. However, due to the available viewpoints, it is unclear if there are overlapping CMEs headed to the E/SE in all coronagraphs. The sources include a small filament eruption visible along the E/SE limb in GOES SUVI 304 starting around 2025-12-07T05:00Z with liftoff closer to 2025-12-07T06:00Z, or the more likely source of an area of brightening visible in GOES SUVI 284 starting around 2025-12-07T05:52Z near S10E50 with an area of brightening to the north of it. These two eruptions appear to be sympathetic eruptions and may be magnetically connected to each other.
