Between October 2005 and March 2006 Sean Ellingham and James Valner from the University of York undertook a project to find the position of Goodricke's observatory using the data he recorded. A 1949 study by Sidney Melmore had shown that Goodricke worked from the Treasurer's House (now owned by the National Trust) very near York Minster. By re-creating Goodricke's observations, the two York students were able to conclude that he had observed from the easternmost window of the second floor, looking south towards the Minster. However, records indicate that the Goodricke family had rented rooms from Edward Topham, the then owner of the northwest wing of the house.
