Description

Xasteria was originally created to bring the excellent ASTRO weather forecast of the service 7Timer to your iOS device. With worldwide coverage and one of the best performing astro-seeing models, it is a great tool for all stargazers.

The app has been extended to offer you quick access to all of your favourite weather resources and tools: Clear Sky Charts (for North American users), Clear Outside, Meteoblue, Windy, Astrospheric, Sat24.com, 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).

The main forecast source, 7Timer, is based on 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.
-Wind direction.

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, German 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, iPhone landscape view, lunar calendar, solar eclipse simulator, location manager.

I would appreciate a quick review on the App Store if you are using the app (there will be no popup asking you in the app as I hate those). If you have a specific request/suggestion you can also try the official app page at http://astro.ecuadors.net

Great app for astronomers

I use this app solely for predicting weather conditions for planetary imaging and have found it to be the most accurate single app that I use. I use a lot of methods and apps together to predict optimum conditions for imaging but as for a single app that will reliably predict clear skies this is the one to go for. Great little app.

September 2018 Update:
Love the new user interface from the most recent update. Such a simple concept to make the daylight hours yellow and the night hours black but really helps quickly see what you need to. Great app that is easily the best and most useful for amateur astronomers.

Another great astronomy app

I reviewed polarscope align pro a few years ago and even had a reticule added.
Having used this weather app for a few months I see it has the same ease of use and attention to detail.
I highly recommend this app to anyone, amateur or pro. Far fewer wasted nights with fingers crossed hoping for clear skies.
Plan your viewing around this app and you won’t be disappointed.

Xasteria

I have been using Xasteria for about 2 months and have been very pleased with it, however it has recently stopped working completely. I have tried reinstalling it but it still won’t work. Is there a problem? If it was still working I would have left 5 stars.

Developer Response ,

Hi. The 7Timer service that Xasteria uses as the default source had stopped updating due to changes in the NOAA data stream. However it was fixed, so you shouldn't have any issues. Meteoblue also changed their website, for that an update of Xasteria is required (under test currently).
