Pegasus? What season is the starry sky?

Pegasus is one of the northern constellations, located in the southwest of Andromeda and north of Aquarius. The most striking feature of Pegasus's star map is that its three stars α, β and γ form an almost square shape with Andromeda's α star, which is called "autumn quadrangle". These four stars are all 2m except that the γ star is 3m, so this quadrilateral is very eye-catching in the sky. The trapezium of Pegasus is the brightest star in the northern sky in autumn.
