Kamil Hornoch (Czech pronunciation: [ˈkamɪl ˈɦornox]; born 5 December 1972) is a Czech amateur astronomer who discovered dozens of novae in nearby galaxies. The main belt asteroid 14124 Kamil is named in his honour.
Kamil Hornoch became interested in astronomy in 1984. One year later he started with his scientific observations of comets, meteors, the solar photosphere, variable stars, the planets and occultations. He lives in Lelekovice, a village in the South Moravian Region, the Czech Republic.
Hornoch makes most of his observations from a small observatory in Lelekovice with a 35 cm (14 in) reflector telescope. Although he uses a CCD camera, he is also good in visual estimates of star luminosity, reaching an accuracy of 0.03 magnitude (confirmed by separate photoelectric measurements). He has also been acknowledged for his numerous estimates and measurements of brightness and positions of comets and variable stars, as well as position measurements of minor planets. In 1993 he co-discovered (with Jan Kyselý) new variable star ES UMa.
