Photoelectric Observations of HR Del During Minimum Brightness On the base of photometric observations of the Nova HR Del duringminimum brightness carried out with 70 cm and 2m telescopes of ShemakhaAstrophysical Observatory besides luminosity changes caused by theorbital motion, ultra-shortperiodic (82s +/- 5s) changes of theluminosity, similar to those which are typical for DX Her (71s) and V533Her (63s), have been detected. On the whole this variable star has fourtypes of periodical changes of its luminosity with small amplitudes andit is a binary system with the orbital period variable in time.
