The following values of the quietest and most disturbed days from Jan 1900 to Dec 1934 were derived by J. Bartels from the international character figure Ci. (Ci is used as a less acurate backward extension - before 1932 - of Cp and C9.) * USE CAREFULLY * The values were manually transferred from a manuscript for the never published third volume (with tables) of "Geomagnetism" by Chapman/Bartels.
