We report the ongoing NIR flare of the Blazar PMN J2345-1555, also known as PKS2345-16 and identified with the FERMI source 1FGL J2344.6-1554, it is an intermediate redshift FRSQSO Z=0.621 (RA=23:45:12.5, Dec=-15:55:07.8 (J2000). On October 17th,2010 (JD 2455486.853959), we determined the NIR flux form this object to correspond to H = 14.997 +/- 0.06, that is 0.7mag brighter than the flux reported in the 2mass survey in the H-band. This NIR flux enhancement is contemporary with the activity observed in the Optical and Gamma rays reported in (ATel #2972). We will continue observing this object, as it is included in our long term NIR monitoring program of blazars. We encourage further multiwavelength coverage for this variable source.
