Abstract: Between 2004 November and 2005 January, we organized a small photometric observing campaign dedicated to the RRab star OV And. This star lies very close to other stars in the field. NSVS (Northern Sky Variability Survey) data suggested the presence of the Blazhko effect in this star. The new data reveal that the large discrepancies in pulsation amplitude of the star reported in the literature can be reproduced by applying different reduction methods. We show that only the data reduced with inclusion of the neighboring stars can be considered trustworthy. Nevertheless, we find some indications that the Blazhko effect may exist in this star.
