27270 Guidotti (2000 AY4) is a main-belt asteroid discovered on January 2, 2000 by Luciano Tesi and Alfredo Caronia at the Pistoia Mountains Astronomical Observatory.[1] This asteroid was observed at Modra Observatory in 2008 in order to determine its rotation period however many solutions between 2.6 and 7 hours are possible with the available data.[4] Guidotti is named after Guido Guidotti the founder of the Valdinievole Association of Astronomy.[6]
