Following the report of near-infrared (NIR) flaring of the Blazar PMN J2345-1555 by Carraso et al. (ATel #2977), the source was observed in J, H and Ks bands at the MIRO (Mount Abu Infra-Red Observatory) on 28th and 30th October 2010. The source continues to be in the flaring phase. On 28th October 2010 (UT - 17:30), the NIR flux was determined to be J = 12.9+/-0.3, H = 12.8+/-0.2, Ks = 11.8+/-0.4 and on 30th October 2010, the NIR flux was determined to be J = 13.3+/-0.1, H = 12.5+/-0.1, and Ks = 11.6+/-0.2. Enhanced multi-wavelength activity of this source has been confirmed by Donato et al (ATel #2972), Kaufmann et al (Atel #2986) and Carrasco et al. (ATel #2989). Considering the ongoing activity and highly variable nature of the source, further multi-wavelength observations are recommended.
