Abstract

Special magnetic and allied observations will be made at stations inside and outside the shadow belt of the total solar eclipse of September 21, 1922, by the Department of Terrestrial Magnetism of the Carnegie Institution of Washington, and by various cooperating magnetic observatories, institutions, and individuals. The distribution of the magnetic observatories within the limits of the eclipse and on both sides of the belt of totality is unusually good, as will be seen from the accompanying map taken from the American Ephemeris and Nautical Almanac for 1922 and on which the positions of these observatories have been indicated. These observatories are: North of the belt of totality, Alibag, Dehra Dun, Kodaikanal, and Toungoo, India; Batavia‐Buitenzorg, Java; and Antipolo, Philippines; before beginning of eclipse, Helwan, Egypt; after ending of eclipse, Apia, Samoa; to the south, Port Louis, Mauritius Island ; Watheroo, Western Australia; Toolangi, Victoria; and Christchurch, New Zealand. This distribution is all the more fortunate since the greater part of the belt of totality is over ocean areas.
