We report the ongoing NIR flare of the flat spectrum radio source B22234+28A, a z=0.795 QSO (HB89 2234+282) also a candidate to a gamma ray source CGRaBS J2236+2828. The source was detected in the 2mass survey with H = 16.070 +/- 0.16. Yet, on November 26,2010, JD 2455526.724470, we carried out NIR photometry of this object, our result yields H = 13.431 +/- 0.01. That is a flux increase ratio of ~11, between the two epochs.
