Following the reports of multiwavelength enhanced emission ( Atel #8879,#8893,#8932,#8960) of the high redshift blazar (z = 1.3889) PKS2023-07, also known as BZQJ 2025-0735, associated with the radio source TXS2011-077 and the
Fermi gamma-ray source 2FGLJ2025.6-0736. We observed the object in the NIR on April 19th,2016,finding it with
enhanced fluxes respect to the data available from the 2MASS all sky survey. On MJD 2457497.97697917 the object had a flux corresponding to H = 13.479 +/- 0.04 that is a flux 1.3mag
larger than that reported in the 2Mass catalog. 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.
