Preliminary results of the study of the open cluster Stock 1

This work presents intermediate results from the study of the open star cluster Stock 1. Observational data used to identify probable variable stars within the cluster were obtained at the Maidanak Astronomical Observatory of the Astronomical Institute of the Academy of Sciences of the Republic of Uzbekistan. The GAIA DR2 catalog was used to determine the astrometric characteristics of the cluster stars. We have identified 113 probable members of the Stock 1 cluster, four of which are variable stars. The average values of their proper motions and parallaxes have been determined: +αcosδ=−6.055±0.253 mas/yr, +δ=−0.221±0.243 mas/yr, Plx= 2.433±0.149 mas.
