We have observed a recent NIR flare of the high redshift quasar PKS0454-234. This radio source is cross identified with the gamma ray source 1FGLJ0457.0-2325 and the optical source BZQJ0457-2324.
From observations carried out on December 12th, 2012 (JD 2456274.787581), we determined the following photometric values H = 12.345 +/- 0.03, J = 13.106 +/- 0.04 and Ks = 11.496 +/- 0.07.
These values correspond to the brightest state of this source since JD2454748.968968, when we started monitoring this source at NIR wavelengths. The source much brighter than the previous flare reported by other observers in the NIR in Atel #3722. It has been reported to shown flaring in gamma ray emission (Atel #3703) 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 strongly encourage further multi wavelength coverage.
