N2 - Abstract: The results of UBVRIJHK photometry for the type II-P supernova SN 2018aoq in NGC 4151 obtained from April 4, 2018, to January 14, 2019, with several telescopes, including the 2.5-m telescope at the Caucasus Mountain Observatory of the Sternberg Astronomical Institute of the Moscow State University, are presented. The main parameters of its light curves have been determined. The light and color curves of SN 2018aoq and several well-studied SNe II-P are compared. SN 2018aoq is shown to be intermediate in peak luminosity between SNe II-P with normal and reduced luminosities. Radiation-hydrodynamics simulations of the light curves and velocities of the expanding envelope of SN 2018aoq have been performed using the STELLA code. The best agreement with the observations has been achieved for SN progenitor models with an ejecta mass (Formula presented.), a mass of radioactive (Formula presented.), and an explosion energy (Formula presented.) erg at metallicity (Formula presented.). The SN progenitor radius depends on the adopted distance D to NGC 4151 and its values are (Formula presented.) at D=20 Mpc and (Formula presented.) at D=16 Mpc.
