Observatory Osokorky ✧ Обсерваторія Осокорки
Using a small telescope (see Equipment), I've been carrying out observation of variable stars. As a side result, new variables have been found, see the list beneath (PMAK V1 .. PMAK V31). More detailed information for some of them can be found in the Variables section.
Many variables in the list below were discovered while data mining the ”Transiting Exoplanet Survey Satellite” (TESS) observations.
These variables have been registered in the International Variable Star Index (VSX), the most comprehensive database of known variable stars.
