We report photometric and spectroscopic near-IR observations (1.08 to 2.3 micron) of the recent 2011 outburst of the recurrent nova T Pyx using the 1.2m Mount Abu telescope and the NICMOS3 imager-cum-spectrograph. Photometric observations were centered around mean times of 2011 April 14.6, 15.6 and 16.6 UT respectively and followed immediately by spectroscopy. In its present avatar, T Pyx quickly brightened from J, H, K magnitudes of (9.88, 9.70, 9.70) on 2011 April 14.6 UT to (7.45, 7.30, 6.94) and (6.81, 6.70, 6.37) on the subsequent two nights (typical error 0.03 mag., note: sky not photometric on 2011 April 14 UT ).
