Discussion:

The circle above is plotted at the expected 105 km diameter of Josephina. With no positive chords we cannot say where the actual path was, so the circle has been plotted on the predicted path.

Some observers had trouble identifying the star as it was expected to be about Mag 14.
However it was in fact much dimmer when using WATEC 120N+ cameras and may have looked more like Mag 16.3. The details can be found on OW Event Details ... Magnitudes Tab shown in the image below.

The partial OW screen image below shows the Star Mag and MP Mag columns and the Camera specific mag beneath.

This effect of (presumably very blue stars) may have been the cause of other Missing Star notes in the past.

Comments: Maybe star fainter than 13.9 - see attached GoogleSky image

 I say maybe because the Google-Sky image shows the target star much-much fainter
 than mag. 13.9, which is the approx. magnitude of the 3 stars in the triangle 
below the stick-pin.  
I could detect the asteroid, and intended to grab an image of the pair well 
separated but hit a technical issue.

Comments: First 3 minutes of intended observing run lost in cloud.  
The magnitude of the target image clearly matched a 13.86 star close by and
 was not 13.1. The target star was not visible.  
Occult  comparison with other catalogs shows no UCAC4 magnitude, others were
at about 17.8, so not visible.
