|The variable star NSV 14523 was discovered by Pinto & Romano (1973) who gave very
rough coordinates but published a finding chart. It can be identified with USNO-B1.0
The star may be identical to the object PB 5349 in the catalog of
faint blue stars at high galactic latitudes (Berger & Fringant, 1980).
Pinto & Romano believed the star to be a peculiar object: though they derived a period
of 0.48176 days, the light curve from a small number of photographs demonstrated
scatter and discrepancies.
We observed the star with the Astrotel-Caucasus robotic telescope (D=300 mm, F=2310 mm) equipped with an unfiltered STL-11000M CCD camera. USNO-B1.0 0963-0597131 (R1mag=16.65, R2mag=16.24) and USNO-B1.0 0964-0599360 (R1mag=15.82, R2mag=15.54) were respectively the comparison and check stars. Our observations allow us beyond doubt to classify NSV 14523 as an RRAB star with the following light elements:
HJDmax = 2454459.263 + 0.48186 x E.
