Measuring Sky Brightness

A program to measure sky brightness in Missouri.


Sky Brightness Measurement Program

Our Chapter has partnered with Truman State University in Kirksville, MO, to offer two exciting programs that provide public institutions such as parks, recreational areas, educational institutions and municipalities with "Sky Quality Meters" ("SQM") to measure sky brightness at their location. Data collected by these SQMs will be used in scientific analysis and to develop programs to reduce light pollution.  Funding for the purchase of the SQM's is provided by the NASA-Missouri Space Grant Consortium. 

Take Action:

If you already have an SQM and would like to contribute your measurements to our study, please Register Your Site.

If you are interested in applying for a one-year loaner under our program, please Apply.
