V. Venkat and B. G. Anandarao, Astronomy and Astrophysics Division, Physical Research Laboratory, Ahmedabad, report near-infrared photometry done at Mt. Abu Observatory's 1.2-m telescope (+ NICMOS infrared array) during Nov. 21.848-21.883 UT on the eruptive young stellar object V1647 Ori. The object was very recently reported to be in its strong outburst phase from optical observations (IAUCs 8968, 8969) after having recovered from the earlier outburst during 2004-2005 (Acosta-Pulido et al. 2007, A.J. 133, 2020, and references therein). These recent observations, made on a very clear and photometric night, confirm the outburst phase, showing magnitudes in J = 10.8, H = 8.9, and K' = 7.7, with typical errors of less than ± 0.1 mag in each band; these values are very close to those at its brightest phase during the 2004-2005 outburst and are much brighter than those in the quiescent phase. The corresponding current infrared images clearly show the presence of McNeil's nebula around V1647 Ori. Follow-up observations are planned.
