We call attention on our recent observation of the Gamma Ray source 2FGLJ1454.4+5123 related with the quasar SBS1452+516 (z=1.0831) with the CANICA NIR camera on the 2.1m telescope at the Observatorio Astrofisico Guillermo Haro, located in Cananea, Mexico. On May 24th,2014,(JD2456801.956), we found this blazar to be in another outburst. It showed fluxes about 1 magnitudes brighter than our previous NIR photometry. On this date the source had J = 14.307 +/- 0.05 , H = 13.612 +/- 0.03 and Ks = 12.867 +/- 0.03 , the source is brightest since the time we started monitoring it on JD 2455689. This flux in the Ks band, is a factor of 3 times larger than the flux observed on JD24556463 (Ks = 13.851 +/- 0.03), with the same instrument. It is a quite significant increase in luminosity in this lapse. This source has being flaring in the past, we reported previous activity of this source in ATEL # 3347 We encourage further multiwavelength observations.
