Sky temp = -38 deg C
I thought that it felt colder than usual as I walked out to the observatory just 5 minutes ago. A quick check of the sky temperature on the infrared thermometer showed it to be -38 deg C. The coldest that I've previously seen was -36, and it's usually closer to -30 at this time of year.
Does anyone else keep tabs on the sky temp? I am just using a $50 gun that was on special at Bunnings one day.
