Status: R

     I may be one of the few people who can do photometry on objects as bright
as Nova Aql 1999 no. 2.  A quick set of measurements with the Lowell 53cm
reflector and Stromgren filters yields the following values using the primary
standard HD 188728 as a differential comparison star:

  UT Date        V    b-y
1999 Dec 2.07   5.03  0.40

Uncertainties about +/-0.03 in each due to the approximate nature of the
zero-point adjustment and abysmal seeing (~20") due a frontal passage just
two hours prior.  The two settings on the nova several minutes apart agree
within 0.02 mag. in V and b-y.
