Solar observations carried out at the INAF - Catania Astrophysical Observatory
Abstract
Solar observations at the INAF - Catania Astrophysical Observatory are carried out by means of an equatorial spar, which includes: a Cook refractor, used to make daily drawings of sunspot groups from visual observations; a 150-mm refractor with an Hα Lyot filter for chromospheric observations; a 150-mm refractor feeding an Hα Halle filter for limb observations of the chromosphere. The photospheric and chromospheric data are daily distributed to several international Solar Data Centers. Recently, a program of Flare Warning has been implemented, with the aim of determining the probability that an active region yields a flare on the basis of its characteristics deduced from optical observations. Some science results obtained by means of solar data acquired at the INAF - Catania Astrophysical Observatory, as well as by space-instruments data, are briefly described.
