Artificial Light Notes:
I observed 3 separate fireflies blinking while I look my dogs out for the night. Prior to me turning on the outside lights, there was ony the streetlight and the permanent led holiday lights on my neighbors house.
This was in my front yard, I did not go into the back yard to check for any.
