101 Virginis is a red giant variable star in the Boötes constellation, currently on the asymptotic giant branch.[1] It was originally catalogued as 101 Virginis by Flamsteed due to an error in the position.[2][3] When it was confirmed as a variable star, it was actually within the border of the constellation Bootes and given the name CY Boötis.[4]
The variability is not strongly defined but a primary period of 23 days and a secondary period of 340 days have been reported.[5]
CY Boo is listed in the Hipparcos catalogue as a "problem binary", a star which was suspected of being multiple but for which the Hipparcos observations did not give a satisfactory solution. Further observations have always shown it to be single.[6]
