Chromospheric network properties on short time scales from PSPT images


Three sequences of Ca II K images obtained on May 3, May 19 and June 7, 1997 with the PSPT (Precision Solar Photometric Telescope) instrument at the Rome Observatory have been used to study variations of the chromospheric network on a short time scale. We have applied to each PSPT image an automated algorithm developed to derive the skeleton representative… (More)
