ADC_Keywords: Stars, variable ; Infrared sources ; Photometry, UBV Abstract: The results of extensive time-series photometry of a new variable star, 2MASS 06451725+4122158, are presented. The B, V observations (over 4000 individual measurements) were made over 23 nights between 2006 and 2007. To investigate the star's physical characteristics additional Stroemgren photometric observations (uvbyHbeta) were made on another four nights in 2007 and 2009. Thirteen frequencies were found from a multifrequency analysis of the V and B photometry. All but two of the frequencies, 19.99716cycles/d (corresponding to the pulsation period of 0.0500071d) and 25.84662cycles/d (0.0386898d), have been identified as combination frequencies. Description: Optical photometric observations of 2MASS 06451725+4122158 were made using the BOAO 1.8m telescope in Korea and the LOAO 1.0m robotic telescope located in Arizona. At BOAO, V band CCD images were obtained on 16 nights, from 2006 January 3 to 2007 February 14. At LOAO, both B and V images were made on seven nights, from 2006 January 6 to 13. The overlapping observations from the two different time zones enabled observations to be made of the stars uninterruptedly for as many as 19hr in a day (2006 January 6-7).
