Discussion:

The circle above is plotted at the expected 134 km diameter of Lampetia. With one positive chord and a nearby miss we can be sure of the path and that the path was south of the predicted line.

Comments: Did not see joining as found star late, though no cloud, 
the star was very low and air contained a lot of pollen so seeing 
poor and I was unable to  get an accurate parting of star and asteroid.
