Description:
In Draco, at ~ 4°E of Thuban (Alpha Dra). Splendid double star whose components
are observed individually without difficulty at 9x. In the first seconds of
observation, the secondary and primary appear the same brightness to me. By
continuing the observations, the primary star is slightly brighter (in fact,
there is a difference of 0,4 magv between the two). They are both white.
