More data of solar eclipses ; Improvement from 9.1 : Resizable graphic part ; Improvement from 9.0 : Better control by keys solar system , better way to adapt new values of Delta_T and information about actual leap seconds.  Improvement from Astronom 8.4 : Better way to locate daylight saving times (DST) ;  synchronizing the time from internet (atomic) time servers ; more accuracy in delta_T . Improvement from Astronom 8.3 : Astronomical assistant ; more data about Lunar eclipses . Improvement from Astronom 8.2 : More relevant data about delta_T ; Moon librations ; more print options.)

ASTRONOM provides a host of data on the positions of the Sun, Moon, and planets seen from anywhere on Earth. Information, plotted on an altazimuth chart and accompanying tables, includes local sunrise and sunset times, solar disk size, Earth-Sun distance, Moon phases, equatorial coordinates, a planetary ephemeris, and an eclipse locator. The positions of the planets may be changed in steps of a second, minute, hour, day, week, and month, or follow the system clock. The software is available from the Internet for a maximum of 3-month evaluation period. Min.
