Low resolution spectra, despite being taken through cloud (at UT 11:45, 2 
Jun 11) shows clear presence of an H alpha emission line.

Possible nova in Scorpius

Images obtained in BVRI on 110602 around 11:30UT confirm the presence of 
this possible nova.

Astrometry using MaxIm and a UCAC2 background, giver the following J2000 
position:

RA: 16 55 09.47
DEC: -38 38 04.4

(Ave residual 0.1arc")

Magnitudes (untransformed) are:

B 12.58 +/- 0.04
V 10.95 +/- 0.02
R 09.70 +/- 0.01
I 08.55 +/- 0.05

An image can be viewed on my website:
