INFRARED OBSERVATIONS OF NOVA SAGITTARII 2012 = PNV J17452791-2305213 Ashish Raj, N. M. Ashok, D. P. K. Banerjee and V. Venkata Raman, Physical Research Laboratory, report near-infrared J-, H-, and K-band photometry of the Nova Sgr 2012 (cf. CBET 3089) obtained with the Mt. Abu 1.2-m telescope (+PRL Near-Infrared NICMOS3 Imager/Spectrometer). The preliminary reduction of these Mt. Abu observations of 2012 April 29.978 UT and May 1.896 UT shows the declining trend in the brightness of the nova in the JHK bands. The JHK magnitudes for April 29.978 are 9.15, 9.01, 8.17 and May 1.896 are 9.65, 9.45, 8.57 with the typical errors estimated to be +/- 0.04 mag respectively from the photometry.
