European Solar Observatory Sunspot Databases and Solar Physics

SDO | Solar Dynamics Observatory
satellite-based sunspot data production


Welcome to the homepage of the Heliophysical Observatory, Debrecen

The observatory is part of the Konkoly Thege Miklós Astronomical Institute (Konkoly Observatory) of the Research Centre for Astronomy and Earth Sciences of the Hungarian Academy of Sciences. The observatory conducts scientific research in the fields of solar activity, heliospheric processes and solar-terrestrial connections. The main products of the observatory are the most detailed existing sunspot databases. These are produced partly from our own ground based observations and partly from space-born observations taken by the SOHO/MDI and SDO/HMI instruments.
