We report the recent NIR secondary light flare in the blazar BZU0742+5444, cross correlated with the radio source FSQR GB6J0742+5444 and gamma ray source 4FGLJ J0742.6+5443. On February 9th,2026 (JD2461080.8182) we found the object undergoing a new outburst. At this time. the NIR flux in the H band was: H=12.471+/-0.03. While the NIR flux in H band on JD2461076.9208 had been H=13.344+/-0.03. Hence, the object has doubled its luminosity in the H band in this rather short period of time. The object has reached again its historically maximum light, (see ATel#17634). Our observations are carried out with CANICA a NIR camera on the 2.1m telescope at the Observatorio Astrofisico Guillermo Haro, which is operated by the National Institute for Astrophysics, Optics and Electronics (INAOE, Mexico). We encourage further multiwavelength observations.
