Observations
of the poorly studied dwarf nova NSV 15086 NSV
15086 is a poorly studied and rather neglected
possible dwarf nova (UG:), with a listed magnitude
range of 14.1 - 15.1. The object is also included in
the First Byurakan Survey catalogue of galaxies with
UV continuum (Markarian galaxies), as FBS 0022-021.
The object was
reported [vsnet-campaign-dn 3083] to be undergoing a
brightening on 2002, Dec 7.576 UT by Andrew Pearce,
who observed it at visual mag 14.8 (he reported it
<15.0 four nights earlier).

I included NSV 15086
in an unfiltered CCD observing session on 2002, Dec
8/9, for a total of 2.6 hours. I used the 35-cm
f/6.3 telescope and ST-7 CCD of CBA Belgium
Observatory.
The object was around mag
15.6
(unfiltered mag) during the run. The resulting light
curve, shown at left, is nearly constant and shows
no modulations > 0.1 mag over the observed
time span. |

Follow-up
observations are strongly encouraged to determine
the further behaviour of this variable star.
