TitlePaper, 'Sun-spots and terrestrial phenomena. II. On the variations of the daily range of the magnetic declination, as recorded at the Colaba Observatory, Bombay [Mumbai]' by Charles Chambers
Date1881
DescriptionChambers writes: 'The present, like the preceding, investigation is on the model of one by Dr Balfour Stewart, dealing with similar records obtained at the Kew Observatory. The records extend, in the present case, from June 1,1847, to December 31, 1872, and consist of differences (always taken to be of positive sign) between the highest and the lowest values of easterly declination observed by Grubb’s declination magnetometer on every observation day of the period. Until the end of the year 1865 the observation day was the Göttingen astronomical day; after that time it was the Bombay civil day. The daily differences were obtained from hourly observations made on all days except Sundays and a few holidays in each year.'
