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 October 31st, 2013 (JD 2456596.953449), we determined the following photometric values H = 12.348 +/- 0.03, J = 13.064 +/- 0.02 and Ks = 11.551 +/- 0.06. These values are almost identical to the brightest state of this source reported in Atel#4647. Our previous NIR photometry of the object (JD2456328.660324) yielded the following values: H = 13.72 =/- 0.05, J = 14.461 +/- 0.02 and K = 12.853 +/- 0.06. Hence, the source has increased its flux by more than a factor of 2 in the last 70 days. Again,
the source is much brighter than the previous flare reported by other observers in the NIR in Atel #3722. In the past, 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 multiwavelength coverage.
