Supplementary data 3 of Hayakawa et al. (2022, Astrophysical Journal, 928, 32) 'Temporal Variations of the Three Geomagnetic Field Components at Colaba Observatory around the Carrington Storm in 1859'. 

This file shows the Colaba Sq variations in August 1859. These data have been reconstructed from the Colaba yearbook (Fergusson, 1860). Their time stamps are given in the astronomical time of the Göttingen Mean Time (GöMT = GMT + 12h 40min), following the original tabulations in Fergusson (1860). The data gaps have been signified as N/A.
