This report describes magnetic investigations made at East Arm, for the purpose of determining whether a certain area would be suitable as a site for an aircraft compass swinging base. A similar survey was made on an adjoining area in December, 1944 (Report No. 1945/1) where magnetic conditions were found to be satisfactory but for other reasons the general design was altered and the site of the proposed swinging base was moved from that area. On 9th June, 1945, a request for investigation of the new site was submitted. The instruments used and the methods employed were similar to those used in the December survey and the report on that survey should be consulted for details of the same. The results of the survey are discussed here. Two accompanying plans are included.
