101 Virginis is a red giant variable star in the Boötes constellation, currently on the asymptotic giant branch. It was originally catalogued as 101 Virginis by Flamsteed due to an error in the position. When it was confirmed as a variable star, it was actually within the border of the constellation Bootes and given the name CY Boötis.
The variability is not strongly defined but a primary period of 23 days and a secondary period of 340 days have been reported.
CY Boo is listed in the Hipparcos catalogue
