Following the report of possible outburst of the star FS Aurigae (AAVSO Special Notice #226), the photometric observations were carried out in near-infrared J, H, and K-bands on 2010 December 5.89 UT, 6.87 and 15.86 UT using the 1.2 m Mt. Abu telescope operated by Physical Research Laboratory, Ahmedabad, India. The photometric observations were carried out in photometric sky conditions. The J-band magnitude of the star was found to be 15.21+/-0.11, 15.34+/-0.45 and 15.48+/-0.49 on 5th, 6th and 15th December 2010, respectively. The H-band magnitude of the star on 15th December 2010 was estimated to be 15.21+/-0.24. The star was below the detection limit in K-band during all three nights of observations. Our observations show the gradual decreasing trend in J-band brightness since the beginning of the observations.
