plotted SQM data for one year

Plotted a full year's worth of Sky Quality Meter data with our SQM-LE meter at the Carr Astronomical Observatory. The orange line is a polynomial trend line on an order of 4.

SQM-LE readings line chart for 2016

Strange readings at the end of the year with a number of very high readings and then tapering off in December (no surprise there).

There were back to back readings on 1 December over 22. Snow piled on the top perhaps? On 9 November there were readings over 22 and then a few over 23! I'd have to go back and look at the weather reports...
