We report on a recent NIR flare of the high redshift (0.996) FSRQ HB891308+326,cross correlated
with the Gamma Ray source 1FGLJ1310.6+3222 (FSRQ OP31) and the optical source B2 1308+32.
On May 10th,2022 (2459709.8078) we found the source at flux maxima J = 13.019+/- 0.059,
H = 12.188 +/- 0.061 and Ks = 11.419 +/- 0.08. These fluxes correspond to a historical maxima
of NIR fluxes since the time we started monitoring the source on JD2454891. A detection
of the source by Fermi-Lat has been reported in Atel# 15483.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.
