This ia a wide path, long duration, high rank event. The duration is 6.0 seconds, and in a dark sky we can integrate long. The target star has no UCAC4 magnitudes, but V and R are given in OWc page, which I've averaged to get a W=13.1, but added to the asteroid, is W=12.6 combined; will drop to G=14.3 mag.
Alt=59, Az=270 due west, Halfway between the Pentagon and Gemini

Successful recordings for all 3 of our team
The below analysis is just a simple square wave. However, there's indication in both Kirk and my curves for some combination of Fresnel diffraction and a binary star as well. But his drop to zero happened at the beginning of the D, and mine was more like mid-way during the occultation. Can I make a stellar brightness and positions model to make sense of this? Anyway, here's the straight-forward square wave D and R.

I got a 5.6055 sec event for Luthera, from home at 16x.
I thought I had it set to 8x, which would have worked, but I found I recorded at 16x.
