sort of smoky and hazy here today so probably compromised air quality tonite too. sometimes the local park dept. dims or turns off lights
when night sky viewing is priority. (although forest fire activity does
decrease at night, and smoke "lays down" .

see international dark sky association IDSA web site has a night time map of the planet from space..you can see all major metropolitan areas by the
light they eminate..all land masses are lit up by this...

there is a movement to reuire public lighting to be shileded from shining up...funny, you'd think that would be a no-brainer...why light up the sky??!!
