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 March 7th, 2017, epoch JD2457819.70115 we determined the flux in the H band to be 13.053. That is 2.5 magnitudes brighter than the flux determined by the 2mass survey. It has had a large flux increment since the epoch JD2457806.73 when we found this object at a flux level corresponding to H = 13.837 +/- 0.03. The activity of this object had been reported previously in Atels #4424 #4528,#4531,#4546,#4724 #4998 #7117,#9672. 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.
