8 ADDITIONAL COMMENTS:
  GPS log checked - true sync is obtained. 

  At T-20min, the target star wasn't see on screen with 0.5s. I took some 5 sec exposures and confined the asteroid
  was approaching the star.  At T-2min the combined target magnitude was seen clearly. An increase in altitude helped.
  The monitor showed a slight drop in light with the star faintly visable.

  Sure of the event.   The AOTA time is reported.
