Sky brightness, VIIRS and SQM
Description (

)
The map displays VIIRS/World Atlas/Clouds/Aurora/IAU observatories and the user SQM measurements. The primary use is to show VIIRS/DMSP data in a friendly manner, but over time it also included some other interesting overlays that concern light pollution like SQM/SQC, World Atlas 2015 zenith brightness, clouds, aurora and IAU observatories. If you have a permanent SQM reader installed you can add it to the map by sending me an e-mail. If you want an analysis of radiance (VIIRS/DMSP) changes over a period of time, then please use the Lighttrends application (look under Help). Please send comments and requests for new features via email (look under help) Functionalities: - VIIRS, Sky Brightness (World Atlas 2015), Cloud coverage and Aurora forecast layers - VIIRS and Sky Brightness layers can be displayed in color blind friendly colors - Road & Satellite base maps - Cloud animation for the last 12 hours - Get detail radiance and SQM values from layers at a click. For World Atlas 2015, you also get Bortle class estimation. - SQM, SQM-L, SQC, SQM-LE, SQM readings submitted by users - Submit your own SQM (L) readings - Observatories layer - Save your favorite locations - Distance measurement tool with azimuth angle report - Offline mode (Sky brightness map and a base map are saved to your device, so it will be displayed when you are offline)}

Website version is bloated with ads, but the concept is really good, so I wanted to buy the app. On my iPad on the website I can find closest dark site, and filter world atlas on an SQM range, all of that seems to not be available in the iPad app ? Why is that, those tools are so great to spot good sky site near you.

Screen went solid white. Had to uninstall and reinstall. Now I have the position map, but not base layer - so I cannot tell what locations correspond to the colors.

I've always relied on the web app for checking light pollution levels, and it has consistently been my go-to resource. Now with the dedicated mobile app, the experience has only gotten better. The app is incredibly user-friendly, offering quicker access to real-time data and a more seamless interface compared to the web version. Plus, it's a one-time purchase with no hidden in-app charges. It’s an essential tool for stargazers and astrophotographers alike. Clear Skies!

I like the app but the most recent data, VIIRS 2023, is only on the website making this app useless as of now. Hopefully it will be added soon.

Jurij: Great app! Certainly a very useful tool for all kinds of things. I found it as someone had linked to it from Reddit. People like to know where to go to stargaze, or see the northern lights. Take care!

Velik trud je uložen u ovu aplikaciju, isplati se podržati autora. Esencijalna informacija za svakog astronoma amatera je upravo kvaliteta noćnog neba. Bilo bi zgodno da 2025. imamo novu verziju “world atlasa”, da vidimo razliku u odnosu na 2015.
