THE EDGE OF NIGHT
(Fall Session)

Friday 15 November from 4:45 pm to 6:45 pm CST
No admission fee. For all ages.
Binoculars strongly encouraged.

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?

There is no other time like twilight. Bring it into your life!

{The various twilights will be explained.}

Celestial Objects in Order of Appearance (with magnitudes):

Venus♀ [-3.9] / Jupiter♃ [-1.8] / Vega [0.0] / Saturn♄ [0.5] / Altair [0.7] / Deneb [1.2] / Polaris [2.0] / Albireo [3.2] / Andromeda Galaxy [4.5]

NOTE: The Natural Sky Conference (which takes place the following Friday) is an excellent followup to this session.

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
