摘要: The primary task of the Debrecen Heliophysical Observatory (DHO) has been most detailed, reliable, and precise documentation solar photospheric activity since 1958. This long-term effort resulted in various catalogs based on ground-based space-borne observations. A series sunspot databases on-line tools were compiled at DHO: Photoheliographic Data (DPD, 1974 –), dataset Michelson Doppler Imager (MDI) Solar Heliospheric (SOHO) called SOHO/MDI-Debrecen (SDD, 1996 – 2010), Helioseismic Magnetic (HMI) Dynamics (SDO) SDO/HMI–Debrecen (HMIDD, 2010 – ). User-friendly web-presentations developed to visualize search data. As a last step compilation, revised version Greenwich Results (GPR, 1874 – 1976) catalog was converted DPD format, homogeneous database covering more than 140 years created. images for GPR era completed with full-disc drawings Hungarian historical observatories Ogyalla Kalocsa (1872 – 1919) polarity Mount Wilson Observatory. We describe main characteristics available data tools.
