We report on a NIR flare of the intermediate redshift quasar CGRaBSJ0948+0022 (z=0.584), associated with the Gamma-ray source 2FGLJ0948.8+0020. Our recent NIR photometry for this source shows that on March 14th,2015 (JD2457095.7981), the object brightness corresponded to H = 14.911+/- 0.07. The NIR fluxes in the NIR bands has increased by 1.2 mag since our previous determination (H = 16.066 +/- 0.03) for JD2456804.7. Hence the object has increased its luminosity by a factor of 3 in this lapse. The object has shown flaring activity in different wavelength bands in the past (see Atel #3429, #3498, #4659 #4694) 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.
