Xasteria: Astronomy Weather5.2 - App Store

Xasteria helps you decide if tonight is worth observing. It brings together astronomical weather forecasts, sky conditions and observing tools in one ad-free app, built around the 7Timer ASTRO forecast.

Configurable forecast sources:
. 7Timer / GFS, worldwide coverage, ~20km resolution:
. Cloud cover (with layer breakdown)
. Astronomical seeing
. Atmospheric transparency
. Temperature and humidity
. Rain / snow
. Atmospheric instability
. Wind speed and direction
. MET Norway, based on the ECMWF model, particularly useful in regions with significant terrain variation
. Multi: combines MET Norway’s short-term forecast with 7Timer astronomy data. Disagreements are highlighted.

Sun/moon details:
. Sun / Moon rise, set and twilight times.
. Moon phase and elevation.

Tools:
. Aurora forecast, with worldwide and local data/maps.
. ISS and satellite passes for your location, plus NASA’s ISS Live Feed.
. Interactive Light Pollution map using World Atlas 2015 or Xasteria/VIIRS 2025 data.
. Quick access to Clear Outside, Meteoblue, Windy, Astrospheric, Sat24, water vapor satellite imagery and more.

Display
Three display modes: 7Timer icon/graphic view, color-stripe view, or raw text. The left panel can be switched to icons, and summary icons and cloud layers are configurable in settings.

This app will always be ad-free, with no in-app popups asking for reviews. If you would like to support it and the 7Timer service, Xasteria Plus adds an Apple Watch app, Home Screen widgets, OpenWeather real-time forecasts, Apple Weather, satellite maps and tracking, night vision mode, lunar calendar, solar eclipse tools and more.

Version History • Redesigned Light Pollution tool with an interactive map using World Atlas 2015 or Xasteria/VIIRS 2025 data. Pan, zoom and tap any location for sky brightness and approximate Bortle estimates. Includes road and satellite backgrounds, adjustable opacity, night colours and an expandable information panel.
• New Multi forecast combines 7Timer astronomy data with the optimal short-term forecast from MET.no or Apple Weather, then blends both sources beyond a configurable crossover time for a longer, steadier forecast. Tap marked disagreements to compare the original data.

Support it by rating it!
What's new:

-Fix for NOAA water vapor not loading on some devices - apologies!
-List of recent places holds more (10) and multiple manual locations are stored.
-Xasteria top title is gone to allow more app space, plus other tweaks.

-Added FAQ section in info page.
-The background color on the main weather view now indicates whether it is day/twilight/night .
-Links for GOES-16 Satellite take you directly to the Band 9 water vapor animations.
-Other water vapor improvements including fix for missing "< Back" button. 2.1 09/05/2018 Remember, because Xasteria tries to be nice and never nags you with popups, it gets very few ratings/reviews. So why not help out the app by rating it? What's new:

-iPhone X full screen support.
-Added a Fahrenheit/Celsius setting separate from Metric/Imperial (useful for countries which use Imperial with Celsius like the UK).
-Added FAQ section in info page.
-The background color on the main weather view now indicates whether it is day/twilight/night .
-Links for GOES-16 Satellite take you directly to the Band 9 water vapor animations.
-Other water vapor improvements including fix for missing "< Back" button. 2.0 09/03/2018 Xasteria never nags you with popups about a rating/review, but gets few ratings for that reason, so if you have time for a quick rating/review, that would be appreciated. There is a link to ratings in the settings page if it helps.
What's new:

-The main Xasteria weather service (7Timer!) will now be more reliable, as a brand new Xasteria-funded US-based server is up and running. This version tries that mirror first.
-The NOAA water vapor page got an update, as there was a satellite replacement: GOES-13 (GOES-East) was retired and GOES-16 is now up in its place. 1.12 03/22/2018 As Xasteria never nags you with popups about a rating/review, it gets very few ratings despite the number of users. So, if you use the app perhaps you could consider doing a quick rating/review on the app store.

-Added French localization.
-Quick access to the latest Water Vapor satellite images.
-Improved contrast in some pages. 1.11 08/14/2017 The 7Timer! service is restored.
