myCSC vs Xasteria Plus - Astro Weather Usage & Stats
Carry your favourite Clear Sky Charts (CSC) in your pocket! Amateur astronomers in North America monitor local sky conditions using the CSC web sites which provide a very detailed 48 hour color coded observing forecast chart for cloud cover, transparency, seeing and other factors. This app contains a database of more than 6000 forecast locations in Canada, the USA and Mexico and can check for new updates. The launch screen monitors up to four or five favourite observing locations. Each square represents one hour and the colors vary from dark blue (excellent) to white (very poor) conditions for observing. A red line indicates local midnight and there is a last updated timestamp. Tapping on any preview chart will open a menu of options that allows you to (i) see a more detailed chart with legend, (ii) map the chart location, (iii) open the CSC web page, (iv) select a different chart location to monitor, (v) remove unwanted charts or (vi) share one of your charts via email, text message or social media. Locations Services can help you find nearby CSC locations when you travel.
Refer to Attilla Danko’s excellent CSC web site home page for complete details on interpreting the preview and detailed charts:

Xasteria+ aims to give you quick access to all the weather forecasts & tools you might need in a single app - especially made for those with an interest in the night sky.
It adds the Apple Weather and MET Norway weather sources, and several extra tools and features to the free Xasteria app and was made primarily to fund the 7Timer weather forecast servers. Why not try the free version of Xasteria first - it is completely free with no ads - if you like it, you can support the service by getting Xasteria+ which comes with many extra features:
-Apple Weather configurable hourly/hyperlocal world forecast.
-MET Norway configurable hourly world forecast with cloud layer option.
-Night-vision mode (choice of red/green/blue) with dimmer.
-Lunar Calendar with Sun/Moon graphs and rise/set/twilight.
-Location Manager with choice of location sources (online search, offline database, maps) and access to GPS accuracy/elevation and barometer data (for iPhones/iPads with barometer sensor).
-Solar Eclipses: Find all future Solar Eclipses for any location and simulate them.
-Landscape display mode ability extends to iPhone/iPod.
As with the free version of Xasteria, you get a customizable world forecast from the ASTRO/7Timer service which provides:
-Cloud cover.
-Astronomical seeing.
-Atmospheric transparency.
-Temperature & Humidity.
-Rain/Snow.
-Atmospheric instability.
-Wind Speed & Direction.
Apple Weather and MET Norway forecasts add visibility, dew point and more.
Xasteria provides you with a choice of 3 visualization modes for the data: an icon/graphic display based on 7Timer's ASTRO, the color-stripe graphics similar to some other astro-forecast services and a raw text mode.
Additional features:
-Quick access to selected astro-weather web sources like Clear Outside, Meteoblue, Windy, Astrospheric, Sat24.com, the latest water vapor satellite images and animations, as well as the nearest Clear Sky Charts.
-Light pollution report/maps for your location.
-ISS and bright satellite passes for your location (data from heavens-above.com).
Xasteria is available in English, Greek, German and French. If you would like to translate it to your own language, please contact the author.
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
