POSSIBLE NOVA IN OPHIUCHUS
K. Nishiyama and F. Kabashima, Japan report on IAUC 8950 the discovery 
of another possible nova (mag 11.3) in Ophiuchus on two unfiltered 30-s 
CCD frames (limiting mag 13.6) taken on 2008 May 31.608 and 31.609 UT 
using a 105-mm f/5.6 camera lens.  Their confirming unfiltered CCD 
images (limiting mag 18.5) with a 0.4-m reflector taken around May 
31.628 yield the following precise position:
RA 17h 33m 29.67s DEC -27 01'16.4" (2000)
They add that nothing is visible at this position on Digitised Sky 
Survey red images.
Following an appeal by the Central Bureau several other observers have 
obtained confirming photometry and astrometry of the new variable. 
Additional magnitudes from unfiltered CCD images unless
otherwise noted:
1985 May 13, [19.5 (Digitized Sky Survey red plate)
1991 Aug 11, [20:  (U.K. Schmidt Telescope red plate)
2008 May 11.661, [13.6 (Nishiyama and Kabashima)
2008 May 25.688, [11.8 (Nishiyama and Kabashima)
2008 May 31.765, 11.1 (K. Kadota, Ageo, Japan, 25-cm reflector)
2008 May 31.795, 11.4 (Nishiyama and Kabashima)

Ernesto Guido and Giovanni Sostero report measures for June 2.23UT:
B = 13.9, V = 12.8, R = 11.4 (remotely with a 25-cm reflector near
Mayhill, New Mexico).
