We report the NIR photometry of the QSO PKSJ1553-2422 (z=0.33), identified with the Gamma-ray source
2FGL J1553.2-2422, on JD 2456804.819363, we found the source with flux values J = 14.801 +/- 0.04,
H = 13.958 and Ks = 12.999 +/- 0.05. These fluxes are at least a factor of 2 larger than the flux
we measured on JD 2456462.795, when the source showed H = 14.750 +/- 0.08. The flaring condition was reported in Atel #6238. Oservations we carried out with the CANICA NIR camera on the 2.1m telescope at the Observatorio Astrofisico Guillermo Haro, located in Cananea, Mexico . Further multiwavelength observations are encouraged.
