HNSKY version 3.3.0 with JPL Ephemeris access covering years –13,200 to +17,191

[han59]

Version 3.3.0, (3.3ß37 Linux) of the freeware planetarium program ,,Hallo Northern Sky" for MSWindows is released.

Added support for Jet Propulsion Laboratory Development Ephemeris (like DE430, DE431). The JPL DE431 is covering years –13,200 to +17,191 and is a 2.8 gbyte download but will give highly accurate planetary positions for a very long period. It will be beneficial for planetary occultations. If you only want accuracy, download a reduced DE430 file of 5 mbytes only covering the years 2000-2050. Links are provided within the program, menu settings. See screen shot below.

Secondly the planetary unit is overhauled. Added apparent position to the menu. Updated time menu and added Julian day input.

Keep going!
