Catania Station The equatorial spar is equipped with 3 instruments:  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 H  Lyot-filter (bandwidth of 0.25 or 0.50 Å tunable filter range +/- 1 Å) and a 2048 x 2048 E2V CCD 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 H  Halle-filter for limb observations. 1st SPRING Workshop, Nov 26-28, 2103 Global H-alpha Network Solar Influences Data Analysis Center (SIDC) World Data Center for the Sunspot Index (NOAA - Boulder)

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  Digitized jpeg images of the photosphere, chromosphere (in Hα) and scanned images of the drawings of the photosphere from 1998 to 2010 are available at ftp://inaf-node- 83.oact.inaf.it/ftp://inaf-node- 83.oact.inaf.it/  On request, we provide fits files of the images of the photosphere and chromosphere, which can be used for scientific analysis.  Together with these data, we also provide the flat-field and dark current files. 1st SPRING Workshop, Nov 26-28, 2103
