I was using my home made 18" Newtonian at prime focus (F6) using a PC164 camera and Kiwi- video time inserter.
      This may be pretty dry stuff for many people but these discoveries (about 20 so far) sure keeps me interested and really helps justify my toys!
      I also want to say that I used Occult 4.1 and LiMovie. Can't thank them enough for the wonderful freeware!

The light curve graph shows the steps as the stars disappear behind the Moon. With it we can get an approximate magnitude for the companion and if another observer or observers were capable of recording this event far from me at another position on the Moon limb a position angle for the two stars can be determined.
