We report on recent NIR Flaring event of the high redshift Blazar PKS0502=049 (z=0.954) also known as CGRaBS J0505+0459, associated with the Gamma ray source 2FGLJ0505.5+0501. We obtained NIR photometry for this object on March 29th,2015 (JD2457101.6701) and found it with enhanced fluxes corresponding to J = 13.663 +/- 0.04, H = 12.738 +/- 0.06 and Ks = 12.089 +/- 0.05. While on JD2457095.6634, we had detected this object at J = 15.063 +/- 0.04, H = 14.581 +/- 0.06 and Ks = 13.769 +/- 0.05. Hence, the object has increased its luminosity by a factor of ~5.5 during this lapse.
Our photometry confirms the flare reported by MacPherson et al (Atel#7279). The object
has shown flares in the past see Atel #6633 and #6868. 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.
