We have observed a recent NIR flare of the intermediate redshift quasar CGRaBSJ0507+100 also known as PKS0507+17 (z=0.416), cross identified with the gamma ray source 1FGL J0510.0+1800. On January 11th, 2015, epoch JD2457033.7760, we determined the flux in the H band to be 13.760 +/- 0.05. That is 1.8 magnitudes brighter than the flux determined by the 2mass survey and has had a flux increment of factor of 2.6 since the epoch JD2456739.634 when we found this object at a flux level corresponding to H = 14.82 +/- 0.05. The activity of this object had been reported previously in Atels #4424 #4528,#4531,#4546,#4724 #4998. 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 encourage further multi wavelength coverage.
