설명

The map displays VIIRS/World Atlas/Clouds/Aurora/IAU observatories and the user SQM measurements overlay over Microsoft Bing base layers (road and hybrid Bing maps).

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)

- 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

VIIRS 2023 availible on website but not app

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.

The update should be available now.

Good app

I’ve used the web based version for some time but thought I’d try the app. Overall it’s great. Understanding some of the values being listed and what it means for your dark sky experience takes a little leg work. I had to go and actually read part of the paper that goes along with the underlying data set. For me the salient figure would be the ratio listed whenever you click on a point in the map. This ratio is the ratio of the artificial brightness from pollution over the natural brightness of the night sky. Per the paper looking straight up anything 1% or less is about as good as you’re going to get (middle of the ocean would be 0% but 1% is about as good if not looking at the horizon). Haven’t looked at every feature so far but overall app works great but the lag to get stats when you click on a location gets tedious.

Very Nice

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!
