In June and September 2004, 673 photoelectric ![]() ![]() ![]() ![]() |
Our photoelectric observations were performed between June 14, 2004 and September 19, 2004 (JD 2453171-53268). The 60-cm reflector of the Mt. Maidanak Observatory (Uzbekistan), equipped with a four-channel pulse-counting photoelectric photometer, was used. A description of the observing techniques can be found in Berdnikov and Turner (2004).
We have obtained a total of 673 measurements in system
(Cousins 1976) for 24 Cepheids; observational uncertainties are
close to 0.02 mag in all bands. The light and color curves are
presented in Figs. 1-3. The phases of observations for all the
Cepheids were calculated with the elements from the General
Catalogue of Variable Stars (Samus et al., 2017). The observations
are available in a text file in the html
version of the paper.

to MAI and AGN. We are also grateful to the administration of Mt.
Maidanak Observatory for allocation of a large amount of observing
time for this observing program.
