I have used this LP map for years, and each year from 2014-2016 (and previous years under the old menu) the VIIRS overlay shows the subtle progression of LP, until 2017 when suddenly it is much darker. Something wrong there.
I then looked at the progression around Tuggerah Lakes and it went the other way, getting significantly worse in 2017, which is likely out of character. Perhaps the methodology has change for 2017?
Check your self, go back and look at how your area has changed each year up to 2017.
I prefer SQM readings.

I'll go the 2016 overlay.......gives me 0.05!!!!
I suppose it's just a matter of comparing apples with apples.....if everyone quotes the 2017 figure then hopefully the info will match up
