Nova (?) Sagittarii 1994

Photometry by A.C. Gilmore at Mt. John  with the 0.6-m f/16 Cassegrain.
Marginal conditions: cloud nearby. The nova region was low in a moonlit sky.


      U.T.         V     U-B    B-V    V-R    V-I     Air mass
1994 Feb. 27.68   8.53  +0.97  +1.44  +0.84  +1.55      2.0

The two measures were consistent to 0.03 mag or better. However, because of
variable atmspheric extinction and other problems these results could be
off by as much as +/- 0.1 magnitude in zero point.

I have never seen a nova with such a positive U-B, but the U-B/B-V ratio
does not seem to fit a normal star either.  Perhaps it is a heavily reddened
nova.  Expert comment welcomed.

Sorry no astrometry.  Cloud re-formed over the region and stayed till
bright twilight.

Albert Jones, Nelson, New Zealand got a visual estimate:
