Realtime Night Sky Quality Measurements
for the Town of Jackson and Grand Teton National Park
The green trace is the zenith brightness (?mag?, in TESS-Photometer magnitudes per square arcsecond). The readings we are getting on averaging of around 20 mags put Jackson into the Suburban category for sky brightness. We can do better!
The orange is the ambient air temperature in Celsius inside the TESS-Photometer (?tamb”); and the blue is the sky ‘temperature’ in Celsius (?tsky?).
tamb-tsky is a measure of how clear the sky is, and what the software uses to make a guess about whether the sky is clear or cloudy. If tamb and tsky are similar, it?s probably because there are thick clouds or overcast skies. But when the sky is clear (and cooling radiatively) there?s a big difference between tamb and tsky. It?s not perfect, but it?s a good first-order guess. If tamb < +10? and mag > 10, a resistive heater inside the case switches on to keep water from condensing on the window.
