Light Variations of the B-type Star HD 160202

Light variations of the B-type star HD 160202 in the galactic cluster M6 are presented. A flare type increase in brightness by about three magnitudes in a time interval of 40 minutes was recorded. It is shown that a B-type star in the galactic cluster M 6 went through the process of shell formation and a flare type increase in brightness in a time interval of three years. Similar cases associated with B-type stars were reported in the past; however, they represent sporadic and accidental observations. The observations presented here show a flare-type event with a resolution of five minutes.
