gSky Digest is a desktop application that resides in system tray. Currently only Windows version is available, however there are plans to prepare instalation images for other platforms.
Using system tray will allow in future versions to receive notifications of the most important events, such as eclipses, transits, close coniunctions etc. Currently system tray only provides better application accesibility.
Events and snapshots
All data presented by the application are divided into two groups: events - expressed by dates, and snapshots - expressed by numeric value or description.
The following snapshots are currently implemented: altitude and azimuth, distance, angular diameter, magnitude, solar elongation, Moon libration, Moon phase text, day phase. Still missing are: constellation name, right ascension and declination, airmass, illuminated fraction of disk.
The following events are currently implemented: rise, set and transit times, civil, nautical and astronomical twilights, equinoxes and solstices, Solar eclipses, Lunar eclipses, Moon phases, maximum Moon librations, ascending and descending nodes of Moon orbit, perigea and apogea, perihelia and aphelia, maximum elongations of inner planets, oppositions of outer planets, planetary and Solar coniunctions, inner planet transits.
There are three ways in which time may be set in the application.
Realtime clock mode: Time is taken from system clock. All values are refreshed every five seconds. This is the default clock mode. It is acivated by clicking an icon on the toolbar.
Selected time clock mode: Time is taken from input box displayed on the toolbar. Values are refreshed immediately after the user inputs new time into the box. This clock mode is also acivated by clicking an icon on the toolbar.
Event clock mode: Time is taken from selected event. It is possible to go one event forwards and backwards. This clock mode is activated by right-clicking any date displayed in the application, and choosing Set time option. This clock mode provides opportunity for some interesting analysis, for example altitude of a given planet at sunset in few consecutive days.
