Following the reports of flaring in Gamma-rays (Atel #8721 and Atel #8740) of the sources 3FGLJ10378.5-2821 identified with the high redshift (z=1.066) quasar PKSB1035-28 and FermiJ1654-1055
tentatively identified with the radio source PMNJ1632-1052. On March 1st,2016, we observed both objects in the NIR. we found PKSB1035-28 (MJD 2457448.8185) with the following flux values: J = 15,616 +/- 0.02, H = 14.816 +/- 0.02 and Ks = 13.941 +/- 0.05. The colors are consistent with those of AGNs and worth
mentioning is the fact that in the 2Mass survey there is no source at this position brighter than H = 17.5. The source Fermi J1654-1055 on MJD 2457449.0551, was found with the following fluxes, H = 15.097 +/- 0.03 and
Ks = 14.241 +/- 0.05. again the NIR color agrees with those of AGNs. This source is fainter than H = 17.5 in the 2Mass survey. We conclude that both sources are flaring in the NIR at the time of flux increases in the Gamma-ray regime. 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.
