We call your attention on our recent NIR observation of the intermediate redshift QSO CGRaBS J1700+6830 (z=0.301) also known as RGB J1700+685, cross correlated with the Gamma ray source 2FGLJ1700.2+6831. On June 21th, 2018 (JD2458290.9496), we found this blazar to be in a new outburst. On this date the source was found to have a flux corresponding to H = 13.150 +/- 0.05. It is a flux about 8 times brighter than previous NIR photometry H = 15.458 +/- 0.03 on JD 2457942.8249. Our observations are carried out with the CANICA a NIR camera on the 2.1m telescope at the Observatorio Astrofisico Guillermo Haro, located in Cananea, Mexico. We encourage further multiwavelength observations.
