October

Farther along on the line from the Pointers to Polaris and Cassiopeia is a large, nearly perfect square of four stars. This is the Great Square of Pegasus. Pegasus, the Winged Horse, lies almost directly overhead in autumn. Located east of Andromeda; signals the coming of Fall. Because Pegasus flies so fast, his hind quarters can’t be seen.

Partially visible during early October low in the south from 35 degrees north latitude.

South of Pegasus and Andromeda, near Aquarius. Pisces represents two fish tied together by two cords:

• The western fish, a pentagon of stars just south of Pegasus, is an asterism known as the circlet.
• The other fish lies on the opposite side of Pegasus, just under Andromeda.

The brightest star, alpha-Piscium, is known as El-Rischa or the "knot" because it ties the two cords together with the two fish on the opposite ends. Alpha-Piscium lies nestled up next to Mira, a bright variable star of the constellation Cetus the Whale.

Unlike Pisces, the zodiac constellation which consists of two fish held together by a string, Piscis Austrinus is a single fish. Piscis Austrinus is a very faint constellation located south of Aquarius, and is often depicted as drinking from Aquarius’ water jar (but why would a fish want to drink water??). Except for the bright star Formalhaut, Piscis Austrinus is rather unremarkable.

Located south of the flukes of Cetus the Whale. Trace to it by following a line southward from Alpheratz (the corner of Pegasus and Andromeda) through gamma-Pegasi, across Pisces and Cetus. This line will run through Beta-Ceti (Diphda) just before reaching the faint stars of Sculptor (alpha-Sculptoris is only magnitude 4.3). Look for it from northern latitudes barely visible low in the south during September and October.

Five stars appear in a triangle.
