[vsnet-alert 3087] v1195 oph

[Jonathan Kemp <jonathan@cba.phys.columbia.edu>]

We report confirmation of P. Schmeer's observation of V1195 Ophiuchi
(private communications; vsnet-alert 3086).  We performed observations on
UT 1999 June 8 with the MDM 1.3m telescope at Kitt Peak.

UBVRI observations reveal the following at JD 2,451,337.76:

V1195 Oph      comparison star (20 arcsec E, 26 arcsec S)

V   = 16.57    V   = 14.89
B-V = +0.24    B-V = +1.24
U-B = -0.52    U-B = +0.88
V-R = +0.17    V-R = +0.77
R-I = +0.23    R-I = +0.69

V-band time-series observations during HJD 2,451,337.763 -> .915 reveal
a modulation with P ~ 0.068 d and amplitude ~ 0.2 mag.  This confirms the
dwarf nova identification of V1195 Oph and establishes it as a member of
the SU UMa class.

Astrometry with respect to 178 USNO-A2.0 stars in the observational frame
yields the following coordinates:

17 00 21.67  -20 53 33.8  J2000.0  (+- 0.3 arcsec)
