The article presents the results of a photometric study of observational data of a four-componentgravitationally-lensed quasar GRAL J024848.7+191331 observed at the Maidanak Observatory.The light curves of the system as a whole and its individual components are shown. The systemas a whole shows a moderate amplitude of the variability, but the brightness of the componentsvaries more actively, up to 0.25 magnitudes. There were no obvious signs of micro-lensing. Themost probable values of time delays were calculated: ΔtAB=−1.7±1.6 days, ΔtAC=−2.2±1.8 days,ΔtAD=–4.8±2.8 days. These values are consistent with the model calculations found earlier.
