Starwatch: Pisces emerges in the eastern sky as the nights lengthen

Zodiacal constellation is composed of faint stars that represent two fish tied together by a cord

As September nights cool and lengthen, the constellation of Pisces, the fishes, emerges in the eastern sky. The chart shows the view looking east from London at 9.30pm BST on 30 September, shortly after the full constellation has risen above the horizon.

As the autumn proceeds, the constellation will rise earlier and earlier. Pisces is one of the zodiacal constellations, meaning it crosses the sun's annual path around the sky.
