Asterism: a grouping of stars that form a recognizable pattern.

Constellation: Cetus
Right Ascension:  02h 36m 00.0s
Declination: +06° 42' 00"
Magnitude: 5 to 6


This month’s asterism is called the “Question Mark”. It is a finder object and is located in the constellation Cetus. It is between the Pleaides in Taurus, Aires and Pisces, at one end of Cetus.   

In this picture the large circle is a typical finder field of view (FOV). The small circle is the “center” of the Question Mark, the “hook” portion is to the lower right and the “bottom dot” is to the upper left.


This object is on the Astronomical League’s Asterism Observing Program.
