We report that on December 9th, 2025(JD2461019.0415), the blazar PKS0754+100, cross identified with
the Gamma ray source 4FGLJ0757.1+0956, was found at its maximum NIR light in our monitored lapse, started
on JD2455241.86, that is 15.83 years ago. Our recent flux determination for the NIR bands were:J=13.544+/-
0.025, H=12.831+/-0.027 and K=11.944+/-0.024 these values show and important increment, as on JD 2460805.69 the observed fluxes were:
J=14.859+/-0.025, H=13.983+/-0.022 and K=13.183+/-0.035.that is an increment of a factor of about 3.2 in this
laspe. Worth noticing is the fact that the object has returned to its brightness level when we started
monitoring it on JD2455272.79, at such time the fluxes were: J=13.378+/-0.02, H=12.838+/-0.01 and Ks = 11,835+/-0.05. Our observations were carried out with the 2.1m telescope of the Guillermo Haro Observatory of the National Institute for Astrophysics, Optics and Electronics (Mexico), equipped with the instrument CANICA a NIR camera. We encourage further multi wavelength coverage of this object.
