The '''Pine Bluff Observatory''' (PBO) is an [[astronomy|astronomical]] [[observatory]] located in the town of [[Cross Plains (town), Wisconsin|Cross Plains, Wisconsin]] ([[United States of America|USA]]) about {{Convert|24|km|mi|sp=us}} west of [[Madison, Wisconsin|Madison]].  PBO is owned and operated by the [[University of Wisconsin–Madison]] (UW-Madison).  It opened in 1958, and is mainly used by students and faculty of UW-Madison for instruction and research.  PBO also provides a facility for testing new instruments.<ref name=PBOMAIN />  Recent research conducted at PBO includes measuring the lunar sodium tail, monitoring [[circumstellar disks]] around [[Be stars]], and studying the [[interstellar medium|warm ionized medium]].<ref name=2006MIER /><ref name=2011DRAP /><ref name=2011HALF />
