We have observed a recent NIR brightening of the intermediate redshift, PMN J2345-1555, also known as CGRaBSJ2345-155 (z=0.621), cross identified with the gamma ray source 1FGLJ2344.6-1554. On November 26th 2012 (JD 2456257.728738), we determined the flux in the H band to be 12.725 +/- 0.06. That is to be compared with a flux corresponding to H = 13.854 +/- 0.05 for epoch JD2456226.70581.That is an increment of about 1 magnitudes over a month time period. This object has been reported as a multi-wavelength flaring one in the past (Atel #2972, Atel #2977, Atel #2986 and Atel #2989). Observations were carried out with the 2.1m telescope of the Guillermo Haro Observatory operated by the National Institute for Astrophysics, Optics and Electronics (Mexico), equipped with the instrument CANICA a NIR camera. We encourage further multi wavelength coverage
