Hungarian historical solar drawings
The first of them was observed at ógyalla Observatory founded by Miklós Konkoly-Thege (1842-1916). We have solar observations taken here between 1872 and 1891. The orientation of the observations is Terrestrial north is ~ at the top and the EW side is reversed exept for 1872 when usually Terrestrial north is ~ at the bottom and the EW side is correct (North=E, South=D, East=K, West= N or Ny).
The other set of solar drawings was observed at the Haynald Observatory in Kalocsa between 1880 to 1919.
The drawings are also available in an interactive online presentation combined with the data of Greenwich Photoheliographic Results (GPR).

ACKNOWLEDGEMENTS
The digitization of ógyalla archives has received
funding from the European Community's Seventh Framework
Programme (FP7/2007-2013) under grant agreement No.
218816 between Nov 2008 and Oct 2011. The EC contribution to the costs of the SOTERIA
project was 75%, 10% of the SOTERIA-related costs of the Heliophysical Observatory was supported by
the National Development Agency under grant agreement No. BONUS_HU_08-BONUS_HU_08/2009-003, and 15% was the
institutional contribution.
The BW digitization of the Kalocsa material was supported by the Hungarian Science Foundation and the millenial Cultural Heritage Program in 2000. The whole Kalocsa material was rescanned with a colour scanner within the project "TÁMOP 4.2.2.C-11/1/KONV/2012-0015" in 2014.
