Following the report of the Fermi-LAT hard spectrum detection (Gasparrini and Buson,2016; Atel #8812) of the intermediate redshift (z = 0.663) blazar FSQR S4 1800+44 also known as BZQJ1801+4404, cross correlated with the gamma-ray source 2FGLJ1801.7+4405. We carried out NIR photometry of this object, on April 16th,2016 (MJD 2457494.01) we found this source in a high activity state with a flux corresponding to H = 13.644 +/- 0.05, while on MJD 2457299 it had H = 14.509+/- 0.04. Hence, it has had an increment of about 0.9 mag in this lapse. 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.
