As part of our IDA application, we began regularly taking sky quality measurements. We use a Unihedron SQM light meter to take these measurements.
For the application we used data from February – November 2021, which had an average reading of 21.50 using all the data points, and 21.60 when removing the outliers.
Below is a link to the spreadsheet where we store the data for our sky quality measurements, with updates made regularly (last updated October 29, 2022).
