Researches at Mount Wilson Observatory of the Carnegie Institution of Washington relating to terrestrial magnetism
Continuous records of horizontal intensity and declination have been continued at Mount Wilson during the past year. Magnetic character-figures have been estimated from these records and published regularly in Terrestrial Magnetism and Atmospheric Electricity with the character-figures representing solar activity. A comparison of solar and magnetic activity has been made in the notes accompanying the tables of character-figures. No further results or conclusions have been reached since the report of last year.
