The magnetometer was moved to an outdoor location and a specialized enclosure was built. An accessory temperature controller was included to maintain a constant temperature and digital link was created to ferry the recorded data back into the laboratory. During the August-September 2000 refurbishment, the magnetometer was moved from the thermally stable but magnetically

dirty basement laboratory to new magnetically cleaner but thermally unstable location outside and away from any building. Of course, it could not be left outside exposed the elements so an enclosure was built to provide a controlled environment. An accessory temperature controller was included to maintain a constant temperature and digital link was created to ferry the recorded data back into the laboratory. The enclosure can be seen in the accompanying images in various states of assembly to show the different techniques used in its construction. Many of the materials can be found around the house or at a local hardware store at a modest cost. Approximately 4`x3`x2` (LxWxH) in external dimensions, the enclosure consists of a wooden frame built with two-by-two stock covered on the four sides with 0. 25" thick plywood, chip board, or particle board (whatever was available in the junk box. The top was left open to accept a 0. 25" thick plywood lid; the bottom was also left open to accept a false floor. The vertical two-by-twos extended about 6" below the sides with pointed tips and were driven into the ground for anchoring. A quiet, shaded location was found beneath a large native Colorado Blue Spruce tree which was cleared of dead branches. The ground was leveled and excavated to a depth of a few inches. a layer of heavy vinyl plastic was placed over the excavation, small undersized cuts were made at the locations of the...
