We have observed a recent NIR flare of the high redshift quasar 4C+50.11. This radio source is cross identified with the X-ray source 1RXS J035930.6+505730 and the radio source NRAO 0150. From observations carried out on November 11, 2013 (JD 2456608.030504), we determined the following photometric value H = 14.688 +/- 0.03. Previous NIR observations of the object on JD2456187.001782 yielded H = 15.737 +/- 0.06 and on JD2456596.939676 H = 15.267 +/- 0.05. Hence, the source has increased its flux by a factor of about 2 in 12 days. Our 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 strongly encourage further multiwavelength coverage.
