Debrecen Photoheliographic Data for 1986 with image supplements
Abstract
The Debrecen Photoheliographic Data (DPD) is a catalogue of daily positions and areas of sunspots compiled by using white-light full-disk observations taken at the Heliophysical Observatory (Debrecen, Hungary) and its Gyula Observing Station as well as at Kislovodsk (Russia). The present material is divided in two parts. The numerical part contains the measured data and the other part contains the CCD scans of all the active regions on the photographic plates. Every measured spot is marked with the same number in the picture as in the numerical catalogue. The images along with the measured data allow more complex analyses, morphological studies and the comparison with magnetic, Hα and other observations.
