It’s not light, it’s not dark. It’s that special time called twilight, and HRPO wants to introduce you to it!
*Are all sections of the sky the same shade of blue?
*Which stars are seen first?
*Are Mercury☿ and Venus♀ or the Moon out?
*Is that moving object a plane, a satellite or space debris?
*How much actual darkness should I expect in a light-polluted city when twilight has passed?
We begin with the Sun☉ a little over a degree above the horizon and sinking. There is no other time like twilight. Bring it into your life!
This program pre-empts the Friday Night Lecture Series on…
*the last Friday in spring before Daylight Time begins
*the Friday during the week of Independence Day
*the first Friday in fall after Daylight Time ends
