White Light Solar Corona: An Atlas of 1987 K-Coronameter Synoptic Charts, December 1986-January 1988

摘要

The synoptic observing project of the High Altitude Observatory's Coronal Dynamics Program began on 5 August 1980. The data obtained for it are gathered by the Mark III K-coronameter located at the Mauna Loa Solar Observatory, Hawaii, and are published yearly in volumes of 'The White Light Solar Corona: An Atlas of K-Coronameter Synoptic Charts.' The data, in the form of synoptic charts, are extended at both the beginning and the end of each year to provide some overlap with the preceding and succeeding volumes. This is also necessary to provide a complete set of the data organized into Carrington rotations covering a specific time period, since the rotations do not coincide with the yearly calendar. Further, observations are made at the limb, and west limb passage occurs 14 days after east limb passage. Thus, an entire rotation's data requires more than 28 days to collect. As well as the synoptic maps, two additional sections designed to aid the user are included in the volume. As in previous Atlases, the Activity Report Summary for the year and Polar Synoptic Charts are included. Also included the Mauna Loa Solar Observatory Calendar for 1987.
