Abstract:
We study the variability of the optical flux from the peculiar
Galactic source SS 433 based on observations with the Russian-Turkish
1.5-m telescope. We describe in detail the technique of high-quality
photometric measurements with a time resolution of 0.3-1s using an
ordinary CCD. Through test observations of non-variable stars, we show
that atmospheric turbulence introduces no significant distortions into
the light curves. Therefore, such data are well suited for studying
the aperiodic variability of various objects.
Description:
SS 433 was observed at the RTT-150 telescope with a CCD photometer, as
was described above, mainly in the summer of 2005. In addition, a few
observations were also carried out in the summer of 2004 and the fall
of 2005. The observations were performed in the R band.
