We report on a new, recent NIR flare of AO 0235+164 (CGRaBSJ0238+1636) a high redshift blazar (z=0.94), associated with the Gamma-ray source 2FGLJ 0238.7+1637. On December 5th, 2015 (MJD 2457361.78) We determined the flux from this object to correspond to J = 14.106 +/- 0.03, H = 13.253 +/- 0.03 and Ks = 12.465 +/- 0.03. That is about 0.8 mag brighter than the flux value measured by our team previously. For MJD2457350, we determined a flux corresponding to J = 15.555 +/- 0.03 , H = 14.100 +/- 0.03 and Ks = 13.293 +/- 0.03. Henceforth, this QSO has had a significant increase in flux by a factor of about 2 in this short lapse. The object has shown multiwavelength flaring activity in the past (ATEL #7975, #8044). Our observations are carried out with the 2.1m telescope of the Guillermo Haro Observatory of the National Institute for Astrophysics, Optics and Electronics (Mexico), equipped with the instrument CANICA a NIR camera. We encourage further multi wavelength coverage of this object.
