We report on our recent observation of the blazar B3 1726+455, also known as S4 1726+45, and CGRaBS J1727+4530, with the CANICA NIR camera on the 2.1m telescope at the Observatorio Astrofísico Guillermo Haro, located in Cananea, Mexico. On September 16th,2010 (JD2455455.7092), we found this source to be in outburst. On this date the source was found to have a flux corresponding to H = 14.32 +/- 0.06. This source have been observed previously at minimum light on May 17th,2010 JD455333.967 with the same instrument, then the source had a flux corresponding to H = 16.18 +/- 0.09. That is a increment in flux of a factor of 5.5 in about 4 months. We encourage further multi wavelength observations.
