Cleansing flights when air temp was 24 degrees.
I have six hives. Last Sunday afternoon, the air temp was about 24 degrees, with bright sunny skies and no wind.
I was quite surprised to see that the bees were out taking cleansing flights and removing dead bees from the hives.
I thought it was too cold at that air temp, but apparently it was OK, as I saw bees returning to the hives, as well as going out.
Not a lot, mind you, and only from 2 of the six hives.
