Xasteria: Astronomy Weather

Xasteria brings the Astronomical-oriented ASTRO weather forecast of the service 7Timer! to your iOS device. You can use your device GPS for a forecast of your location, or enter manual coordinates. Additional weather sources are offered: Clear Sky Charts (for North American users), as well as quick access to web sources like Clear Outside, Meteoblue, Windy, the latest water vapor satellite images and even light pollution maps. ISS and bight satellite passes for your location are also shown (data from heavens-above.com). 7Timer! is mainly derived from the NOAA/NCEP-based numeric weather model, the Global Forecast System (GFS) and gives you a forecast for the entire globe with a resolution of about 20km at 3-hour intervals. The data provided includes: -Sun/Moon rise/set & twilight times. -Moon phase. -Cloud cover. -Astronomical seeing. -Atmospheric transparency. -Temperature. -Humidity. -Rain/Snow. -Atmospheric instability. -Wind. Xasteria provides you with a choice of 3 visualization modes for the data: the new 7Timer! ASTRO graphics, the color-stripe graphics similar to some other astro-forecast services and a raw text mode. Xasteria is available in English, Greek and French. If you would like to translate it to your own language, please contact the author. Xasteria will always be ad-free. If you would like to support it, as well as fund the 7Timer! service behind it, you can get Xasteria Plus, which can access non-free weather sources and has some extra features like night vision mode, a lunar calendar and a location manager. I would appreciate a quick review on iTunes if you are using the app - if you have a specific request/suggestion you can also try the official app page at http://astro.ecuadors.net
