We observed the field of ZTF23aaoohpy/AT2023lcr (Swain et al., GCN 34022) with the Italian 3.6m TNG telescope equipped with 
the near-infrared camera NICS. A series of images were obtained with the J and K filters on 2023-06-22 from 03:10:54 UT to 04:32:57 UT 
(i.e. at a mid time of about 60117.16 MJD).

At the position of the previously reported optical transient (e.g., Swain et al., GCN 34022, Gompertz et al., GCN 34023, Kumar et al., 
GCN 34025, Adami et al., GCN 34030, Perley et al., GCN 34031, Jian et al., GCN 34040) we clearly detect a source in both J and K filters.

From preliminary photometry we derive K ~ 18.8 mag (Vega; calibrated against the 2MASS catalogue), not corrected for Galactic extinction.
