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 mere seven degrees above the horizon and sinking. There is no other time like twilight. Bring it into your life!
The 16 April lecture “Wonders of the Spring Sky” is an excellent followup to this session.
