IHY activities in Hungary
Heliophysical studies are carried out in 8 scientific institutes and observatories
in Budapest, Debrecen, Sopron, and Tihany in wide international collaboration.
Ground based observations of the Sun have been made in Debrecen, geomagnetic
observations in Sopron and Tihany. The Nagycenk Geomagnetic
Observatory was established in 1956-57 for the International Geophysical Year.
Since the advent of space era Hungarian institutions have been involved
in various fields of heliophysics:
solar and galactic cosmic rays,
the interplanetary medium, interaction of solar wind with planets and comets,
the magnetosphere and ionosphere of the Earth, Mars, Venus,
Jupiter, and Saturn.
They have been involved in various space programmes in Russian collaboration
(Intercosmos, Venera, VEGA, Phobos, Compass-2, etc.), ESA (Ulysses, Cluster,
Mars Express, Rosetta, Venus Express),
French (Demeter), and NASA (SOHO, International Space Station, Cassini) programmes.
The most recent one is NASA's STEREO to study the 3-dimensional evolution of coronal mass ejections.
Future missions include BepiColombo to planet Mercury.
Hungarian scientists have been involved in theoretical studies of the solar atmosphere and interior,
magnetic coupling of solar atmosphere and its effects on interplanetary space and Earth,
numerical simulations of the solar wind-nonmagnetic body interactions, propagations
of solar energetic particles and modulation of galactic cosmic rays.
