Catania Station • The equatorial spar is equipped with 3instruments: • Cook refractor (150/2230 mm), used to make daily drawings of sunspot-groups from visual observation; • 150-mm refractor (2300 mm focal length) feeding a Zeiss HLyot-filter (bandwidth of 0.25 or 0.50 Å tunable filter range +/- 1 Å) and a 2048 x 2048 E2V CCD 42-40 array (in patrol full disk mode the camera can take images every 150 sec), with a dynamical range of 16 bit; • 150-mm refractor (2300 mm focal length) feeding a HHalle-filter for limb observations. • Global H-alphaNetwork • Solar Influences Data Analysis Center (SIDC) • World Data Center for the Sunspot Index (NOAA - Boulder) 1st SPRING Workshop, Nov 26-28, 2103

Solar Observations The Photosphere(Oct 27, 2003) The Cromosphere(Oct 27, 2003) 1st SPRING Workshop, Nov 26-28, 2103
Solar data archive and distribution • Taking into account that solar observations started in Catania more than one century ago, we stress the important heritage provided by the several and different sets of data, like the photographic archives stored at the Catania Observatory. • These archives mostly consist of synoptic full-disk photospheric and chromospheric observations, the latter taken with a spectroheliograph or with birifringent filters, in the CaII K and Hα lines. These observations, stored on plates and acetate negatives, date from 1926 to 1998. • Digitized jpeg images of the photosphere, chromosphere (in Hα) and scanned images of the drawings of the photosphere from 1998 to 2010 are availableatftp://inaf-node-83.oact.inaf.it/ • On request, weprovidefitsfiles of the images of the photosphere and chromosphere, which can be used for scientificanalysis. • Together with these data, wealsoprovide the flat-field and dark currentfiles. 1st SPRING Workshop, Nov 26-28, 2103
