Its diameter is about 19 km and it has an albedo of 0.243 [https://www.webcitation.org/5mqp8r4gD?url=http://www.psi.edu/pds/resource/imps.html]. Its rotation period is 9.336 hours[https://archive.is/20060614093519/http://www.psi.edu/pds/archive/lc.html]. Rosamunde is named for a character in a play of the same title for which Franz Schubert wrote incidental music.[2] References1. ^{{Cite web |url=http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=540;cad=1 |title=540 Rosamunde (1904 ON) |work=JPL Small-Body Database |publisher=NASA/Jet Propulsion Laboratory |access-date=5 May 2016}} 2. ^Lutz D.
