A program of regular observations of solar magnetic fields was started at Kitt Peak National Observatory in April 1973, primarily in response to the needs of the Skylab mission. At first, the observations were made with the 40-channel magnetograph at the McMath telescope. During 1973 a telescope dedicated to synoptic studies was completed, and starting in 1974, observations were made with a 512-channel magnetograph. Daily full disk observations were first combined into synoptic maps during the Skylab Solar Workshop on Coronal Holes and High Speed Wind Streams and were used for studies of the magnetic field strength below coronal holes and extrapolations of the magnetic field into the corona, but these maps have never been published. Starting with Carrington rotation number 1681 the synoptic maps have been produced and published regularly in Solar-Geophysical Data, Part I (National Geophysical and Solar-Terrestrial Data Center, Boulder, Colorado). Old data obtained prior to Carrington rotation number 1681 have now been processed into synoptic maps in the same way as current data are processed, and this publication presents these earlier maps in the same format.
