Bird is the Word
Today we have five questions, so we will take five minutes to complete the quiz today.
With that in mind, ladies and gentlemen, please get out a clean sheet of paper and a No. 2 pencil and prepare for today’s Astronomy Pop Quiz.
DMG procedures and expectations apply; 1) if you find a mistake, please let me know, and b) do your best.
The topic today: the constellation Cygnus
You have five minutes to complete the quiz. Begin now.
What star name means “tail” in Arabic?
Beta Cygni is really a double star. Can you name it?
NGC 7000 is one of the best examples of a bright nebula. What is the popular name for this cloud shaped vaguely like a continent?
M 39 is a loose Open Cluster in Cygnus that was apparently seen by Aristotle. For what does the “M” stand?
SS Cygni is a faint star in Cygnus. The prefix “SS” tells us something important about this star. What?
Extra Credit: Name a bird constellation observers in the USA can not see.

Correct Answers……..Periscope Winners:
Deneb………. @arnoldrimmer: Alpha Cygni is the brightest star in the constellation Cygnus. At 1.25 magnitude, it is also the 2oth brightest star in our night sky. It’s stellar type A2 which indicates a very hot star with a lot of mass.
Albireo…….. @arnoldrimmer: Beta Cygni A is magnitude 3.1 and B is 5.1. A is a nice yellow and B is blue.
The North American Nebula….………@speear40: This wonderful emission nebula appears 120 arcminutes by 110 arcminutes. Use a filter and low power when observing thru a telescope.
Messier…………….@rigsadsege: (Replay shows I was initially wrong declaring the winner for this question. Sorry Melissa. My mistake.) . Charles Messier mad a list to help his comet-hunting friends avoid mistaken announcements. He discovered 15 comets.
Variable star………..no winner: Variable stars were thought to be rare, so when the labeling pattern was invented, scientists thought they would find just a few per constellation. The first in a constellation would be named R , such as R Coronae Borealis. The next would be S, and on until Z. Nine reserved designations seemed they would be enough, but no, it wasn’t.
