ο Ceti

Omicron Ceti is Mira, the Admirable One, or simply ‘Wonderful’, the most notable of all variables.

Mira changes its magnitude from a usual 8.5 magnitude to a very bright 2.2 every 331.6 days.

As the period is very nearly eleven months Mira's annual return to brilliance is a regular occurance eagerly awaited by many amateur astronomers.

To find the star, proceed from alpha, down to gamma and delta, then a binocular and a half southwest to: Mira.

You can also get to Mira from alpha Piscium: drop down one and a half fields southeast of alpha Piscium.

About a degree and a half northwest of Mira is 66 Ceti (Struve 231), with a nice colour-contrast, yellow and blue; AB: 5.7, 7.7; 235º, 16.7".
