A. Rossi, E. Maiorano, E. Palazzi (INAF-OAS), D. B. Malesani (U. Radboud and DAWN/NBI), A. Melandri (INAF-OAB, INAF-OAR), report on behalf of the CIBO collaboration:
We observed the field of the fast red optical transient ZTF23aaoohpy/AT2023lcr (Swain et al., GCN 34022; Gompertz et al., GCN 34023; Kumar et al., GCN 34025) with the LBC camera mounted on LBT (Mt Graham, AZ, USA) on 2023-06-23 in u’g’r’z’ bands at approximately 4:30 UT. A second observation was obtained on 2023-06-26 at 08:30 UT in g’r’z’ bands. Both observations were performed under good weather conditions.
We detect the optical transient in all bands and epochs and we measure the following preliminary AB magnitudes for the first observation:
r’= 22.5 +/- 0.1
calibrated against SDSS field stars, and not corrected for the foreground Galactic extinction.
We acknowledge the excellent support from the LBTO and LBT-INAF staff, particularly D. Thompson, D. Gonzalez Huerta, F. Cusano and D. Paris, in obtaining these observations.
