This Geocentric Tellurion shows an approximation of the current position of the sun and moon according to the time, date and your location on planet Earth. Hover the mouse over the sun or moon images to show the times of sunrise, sunset, moonrise, moonset and civil twilight.
The three left-side control buttons are:
Top: toggle the time/date display on and off.
Middle: fast-forward movement of the sun and moon by condensing one day's movements to 7-8 seconds.
Bottom: Edit the UserVariables.inc file which stores the latitude and longitude of your location. This changes to Pause/Play when in fast-forward mode.
An Auto-Detect skin runs when you first install the Tellurion to set the longitude and latitude according to your IP address. This probably won't detect your actual location so if what you see is not where you really are you will need to edit the longitude and latitude following instructions in UserVariables.inc
Thanks to: Stone
for translating the C-source code for calculation of moonrise and moonset to Lua. Mirage
for testing and pointing out an error in the calculation of timezone. moshi
for reminding us that the moon's image needs to be rotated according to the observer's latitude.
And thanks to the Rainmeter Development Team for continual improvements to the nifty desktop customization tool that Rainmeter is.
You'll need the latest BETA version of Rainmeter to run this skin. Get it from here rainmeter.net/cms/
UPDATE: 22nd April - Fixed the late setting of the moon image on days close to those when the moon doesn't set - thanks to 'Stone' for pointing out the bug.
UPDATE: 25th April - Added option to switch between five different backgrounds by left-clicking anywhere on the background image.
UPDATE: 8th July - Changed AutoDetect.ini to more accurately detect your location from the IP address.
