Abstract : This report concerns the determination of formula and baseline values for the period January 1, 1960 to December 31, 1963 for the H-magnetograph run at Godhavn Geophysical Observatory for Dr. E. J. Chernosky on a contract with AFCRL. Besides bringing the formula and constants necessary for a further study of the magnetograms the report shows the existence of a regular yearly variation of the baseline values nearly in phase with the variation of the air temperature at Godhavn. Since the magnetograph is kept at a constant temperature in a well insulated shelter it is assumed that the dependence on the variation of the outdoor temperature is an indirect one, probably a dependence on the variation of the humidity in the shelter.
