B and V photometry of the eccentric eclipsing binary DI Her is reported, with the aim of contributing to a more accurate determination of the timings required for the ongoing apsidal motion studies. The resulting apsidal motion rate is close to the one reported earlier by Khodykin and Volkov (1989), Guinan, Marshal and Maloney (IBVS 4101), and Yildiz et al. (2000).
