Observations with B,V,I filters of a field centered on the galaxy NGC 7793.
Generally, observations in 2-3 filters are requested for any given night.
The observations in the second (third) filter should follow the observations
in the first (second) filter immediately, to get accurate color information
of the variables.

Observation nights should be spread out over a time interval as long as
possible, because principal scientific aim is to detect long-period Cepheids
from the images. Within this time interval, observation nights should be
distributed as uniformly as possible (avoiding images on consecutive
nights).

For this programme time baseline should be as long as possible.
So, observations for this programme should start as early as possible.

Standard calibrations for BVI filters requested.
