Brighter star

1) Look up the apparent (visual) magnitude of the following stars:
Betelgeuse:
Arcturus:
Almach:
Procyon:
Sirius:
Vega:
2) Calculate the difference in brightness:
Which star is brighter Betelgeuse or Arcturus? By how much is it brighter?
Which star is brighter Almach or Procyon? By how much is it brighter?
Which star is brighter Sirius or Vega? By how much is it brighter?
3) Go outside on a relatively clear night. The star chart is optimized for 1 1/2 hours after
sunset (about 8:30 PM). Write down the date and time as well as your location (just the city
is fine). Also write down what the current sky conditions are like where you are.
4) Look up above you (should be almost straight up!) and see if you can identify the
asterism known as the Summer Triangle. Write down which stars make up the Summer
Triangle as well as their apparent magnitudes. It is OK to use the aid of an APP like
SkyView Light to help identify stars.
5) Make a sketch of the Summer Triangle as you see it. Include any stars that are within the
triangle or nearby.
6) Compare your sketch to that of the star charts you have. Both the star chart from lab 1
and the “what’s out tonight” sky map. Figure out which stars you can see and make a list of
them including their magnitudes. Make a list of the stars you can’t see including their
magnitudes.
