We carried out near infrared observations of the SN2023ixf using CANICA instrument at the 2.1m telescope of the Guillermo Haro Observatory, which is operated by the National Institute for Astrophysics, Optics and Electronics (INAOE, Mexico). The observations were obtained on 4 nights between 30th May and 2nd June in the JHK bands, with typical exposure times of 7x50s, 7x40s, 7x60s in J, H and K bands respectively. The Julian Day (JD) corresponding to the middle of exposures, measured magnitudes in the three bands in the Vega system, and error on each measurements for each epoch of observations are given below:
