Notes:
------
(1) Had two objectives on this full moon hazy night - find #90108
     and check on USA 186.   90108 not seen - max elevation was
     about 12 degrees but sky too bright - city and twilight - so
     not seen.  Expected magnitude about +8.4.  Will try again when
     I get a higher elevation pass and better conditions.

Cheers
Greg
