Abstract
Automatic vertical‐incidence recording of ionospheric heights has been continued at the Watheroo Magnetic Observatory, Western Australia, and at the Huancayo Magnetic Observatory, Peru, of the Department of Terrestrial Magnetism, Carnegie Institution of Washington, from the date of the last report [see 1 of “References” at end of paper] through October 1937 for Huancayo and through April 1938 for Watheroo using a fixed frequency of 4.8 mc/sec. These records have been examined and all radio fade‐outs are listed in Tables 1 and 2.From November 1937 and from May 1938 at Huancayo and Watheroo, respectively, fade‐outs were recorded by means of automatic multifrequency equipments recently installed [2] which replace the 4.8 mc/sec fixed‐frequency recording. Records are incomplete during November and December 1937 from Huancayo and during April and May 1938 from Watheroo because of installation and adjustment of the new equipments.
