ResumoThe Aurora‐Borealis investigations of the Canadian International Polar‐Year party located at Chesterfield Inlet, (63° 20′ north, 90° 42′ west), comprised single‐station visual observations, single‐station photographs of the brighter displays, and double‐station photographs for height‐measurements. To date height‐measurements have been made on 200 of the parallactic photographs, and a study has been made of the visual observations on nights without cloud. The secondary auroral station was located south of Chesterfield on the coast of Hudson Bay. It was established during September, 1932, when it was possible to travel along the coast by boat. A sod shelter, Figure 1, was built, and a supply of food and kerosene left there for future use. The position of this station relative to the Chesterfield station was determined the following spring by triangulation and stadia‐rod surveys over the Bay ice. The values obtained were: Length of base‐line, 33.14 km; azimuth from north, +173° 39′.
