Order Paper NowSee Section 27.1 of the text and then use one of the following on-line star maps either at:
https://www.skymaponline.net/ or
https://www.stelvision.com/en/sky-map/
(note for this one if, you don’t want to register- its OK to use the default NY City location)
(both should allow you to set your location and time. The stelvision buttons are on the right side, the skymaponline buttons are on the upper left)
Depending upon which map you use, the colors will be different for stars and constellations. Make sure you get it correct. For skymaponline, the star names are blue, the constellations are in yellow
Make sure you have it set for Washington DC!
1. Set the star chart for October 18th, at 9 pm (note this is 2100 hours in universal time, the slides show what it should look like). Use this setting to answer the following questions. Might have to “zoom out” to see the entire horizon (the blue edge)
a. Find the constellation Taurus. In which direction in the sky would you look to find it?
b. In which constellation is the star Vega?
c. Give the name of a rising constellation (see slides for “rising” and “setting” discussion)
______________________
d. Give the name of a constellation which is setting
______________________
e. The zenith is the highest point in the zenith for you, the observer. Straight overhead. It is at the intersection of an imaginary line connecting east-to-west and north-to-south.
What constellation is close to the zenith? (Hint: if you say Ursa Minor, you are wrong- that is to the north)
Assignment 7 continued
2. Set the star chart to 9 pm, December 25 (8 pts)
a. What constellation is at the zenith?
b. Locate one rising and one setting constellation. Are they the same as you identified in the fall?
c. Find the constellation Orion. Zoom in and name two bright stars in Orion (hint: one is reddish)?
d. Hit the plus button on the top under “time”. Or, depending on which map, just keep adding an hour to the time. Watch Orion move across the sky. When does Orion vanish beneath the western horizon? This is called the setting time.
3. Name 2 constellations which never rise or set (i.e. always visible all night long), regardless of the season. You might need to advance the star chart throughout the night and see which constellations remain above the horizon. These are circumpolar constellations. (4 pts)
