Our length of day has dropped below 12 hours, here in the Interior of Alaska. 11 hours and 22 minutes, to be exact. The length of visible light has shrunk to 12 hours 59 minutes. Yesterday had 6 minutes and 38 seconds of more daylight.
There have been several hard frosts already, but no snow in Fairbanks. The low, so far at the cabin this autumn, was 22F.
Check those headlamps; it’s all downhill until December 21.
