Smithsonian spectrobolometer building at Mount Wilson Observatory. The wooden building is draped with a white tarpaulin, which provides shade over the windows. A wooden staircase leads to the slightly open door of the building. Some astronomical instruments are on the landing near the door. Several trees surround the building.
