| dbo:abstract | 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 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. (en) 101 Virginis, eller CY Bootis, är en pulserande variabel av halvregelbunden typ (SRB) i stjärnbilden Björnvaktaren. Trots sin Flamsteed-beteckning tillhör den inte Jungfruns stjärnbild. Den ligger på gränsen mellan stjärnbilderna och fick byta tillhörighet vid översynen av gränser mellan stjärnbilderna år 1930 och benämns sedan bytet av stjärnbild ofta med sin variabeldesignation, CY Boo. Stjärnan har en genomsnittlig visuell magnitud av 5,84 som varierar mellan +5,74 och 5,9 utan någon fastställd periodicitet. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 3,4 mas, beräknas den befinna sig på ett avstånd på ca 970 ljusår (ca 300 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radiell hastighet på ca -11 km/s. (sv) CY Волопаса (лат.
