Following the report of the Fermi/Lat detection of a Gamma Ray flare (Hays and Donato, etal. Atel #3313) in the
general direction of the quasar SBS1150+497 (z=0.334). The instrumental beam also included with smaller probability the quasar SBS1149+499 (z=1.093). We observed both objects in the NIR. We found that on JD 2455680.827569, SBS1150+497 had a flux H = 13.515 +/- 0.09, 1.4 magnitudes brighter than the value reported in the 2mass survey. While on JD2455680.752870, SBS1149+499 had a flux H = 15.471 +/- 0.07 very similar to the value 15.58 +/- 0.13 reported in the same survey. These facts, render further support to the idea, that the Gamma Ray emission recently detected by the LAT instrument, comes indeed largely from SBS1150+497. We encourage further multi wavelength observations of these objects.
