Following the report of enhanced Gamma-ray activity by Fermi LAT, we observe the quasar 3C454.3
at NIR wavelengths, finding it with increased flux. On August 22nd, 2015 (MJD 2457256.727951),
the object had J = 12.246 +/- 0.04, H = 11.367 +/- 0.04 and Ks = 10.463 +/- 0.05. These values
correspond to fluxes about 30% larger than the ones obtained in our previous observations on
MJD 2457008. Flaring activity in visible light for this object had been reported by S. Jorstad et al. (Atel#7942). 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.
