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. In Atel #4608, we reported this object as a brightening one in the NIR. Yet, on December 18th,2012 (JD2456279.629815)
it flared again by half a magnitude reaching a flux corresponding to H = 12.231 +/- 0.11. On JD2456226.705810 the object had an H magnitude of 13.854 =/- 0.05.
That is, it shows an increment of about 1.6 magnitudes over a 50 day lapse. This object has been reported as a multi-wavelength flaring one in the past (Atel #2972, Atel #2977, Atel #2986 Atel #2989 Atel #4735). 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
