The paper presents the results of photometric processing of digital images of a new double gravitationally lensed quasar SDSS J2124+1632 observed at Maidanak observatory. The light curves showed that the brightness of the components during 2018-2021 has an active variability caused, among other things, by microlensing. The probable value of the time delay ∆tAB = 105.3±18.8 days was calculated (component B is leading one). This value is consistent with the previously found time delays for binary gravitationally lensed quasars with a similar configuration.
