 We report the discovery of a new variable star in the Lynx constellation. The star is catalogued as GSC 03409-00999 (07 33 08.6, +48 03 53.5). From analysis of the light curve we are induced to think the star may be a RRab Lyrae-type variable. We calculated the epoch HJD0 = 2455644.363 +/- 0.007 and the period P = 0.61971 +/- 0.00003 d, during which the star changes its brightness from a minimum magnitude m_min = 13.65 +/- 0.01 to a maximum one m_max = 13.11 +/- 0.01. The light curve shows the asymmetry 0.248 +/- 0.001, with a rise time tau_ RT = 0.1539 +/- 0.0007 d.

Simbad object(s): GSC 03409-00999,
