J: Jet

Note: Faint minor CME seen to the SW in SOHO LASCO C2 and a couple of early C3 images before it dissipates. The CME is possibly covered by the pylon in GOES CCOR-1 (or too faint to be seen in this coronagraph); it is covered by the daily data gap in STEREO A COR2. Its source could be a minor opening of field lines on/behind the SW limb at the time seen in SDO AIA 193/304/131, and movement of field line behind the SW limb seen in GOES SUVI 284, however this is not a definitive source.
