Scientific paper

We report the ongoing NIR flare of the quasar PKS 0458-02 it is related with the radio source 4C-02.19, and it is likely associated with a gamma ray source CGRaBSJ0501-0159 and the radio source WMAPJ050118-0159. It is a high redshift FRSQSO z=2.286 (RA=05:01:12.81, DEC=-01:59:14.3, J2000).On October 31th,2010 (JD 2455500.97644), we determined the NIR flux from this object to correspond to H = 14.997 +/-0.04, than is 1.7mag brighter than our previous observation on March 26th, 2010 (JD2455281.65087), when we determined it to have had H = 16.687 +/-0.08, that is an increase in flux of a factor of 5.
