7334 Sciurus           Discovered 1988 Aug. 17 by A. Mrkos at Klet.
Sciurus vulgaris and Sciurus carolinensis are squirrels, animals that live mainly in the tops of trees in parks and forests around many observatories, including Klet and the České Budějovice Observatory. The name was suggested by J. Ticha.
