We report on a NIR brightening of the intermediate redshift quasar PKS0306+102 (z=0.863), also known as CGRaBSJ0309+1029, associated with the gamma-ray source 2FGL0309.1+1027. Our NIR photometry for this source shows that, on February 18th,2014 (JD2456706.6940), the object brightness corresponded to H = 15.72 +/- 0.04. This value is about 0.7 magnitudes brighter than our previous photometry, obtained on JD2456678.73 (H = 16.38 +/- 0.07), for this field. Hence, it has doubled its flux in a lapse of 28 days. The object is brightest since we started monitoring it on JD 24546324. Our observations are 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 strongly encourage further multiwavelength coverage.
