\begintext

\IBVSEobs{Photoelectric observations were made in years 2002-2004 with
Maksutov telescope (diameter 350 mm, focus length 3420 mm) at the
Astronomical Observatory of the Jagiellonian University `Fort Skala'.}

\IBVSEdet{Uncooled one channel photometer tube with Russian photomultiplier
FEU 92, and photon counter was used. Observations were made using wide-band
B filter.}

\IBVSEred{The observations were corrected for the dead time effect, and
differential atmospheric extinction, using mean extinction coefficients.}

\IBVSEmethod{The minima times were computed using Kwee method 
(Kwee \& van Woerden, 1956) except observation TV UMi in JD 2452784, 
and HT Vir in JD 2452722, where Gaussian fit was used.}
