Astronomy 102, Spring 2008: PROJECTS

Choose one of the following projects

1. Moon Observation:

Observe the Moon approximately every 3 days or so during the Spring term

Estimate the angular separation of the Moon from the Sun
Note the Moon's phase
In conclusion: Draw a diagram of the Sun-Earth-Moon system that best explains your observations

2. Mars Observation:

Observe Mars approximately every 3 days or so during the Spring term

Estimate the angular separation of Mars from the background stars Pollux, in the constellation Gemini, and Regulus, in the constellation Leo
Using a sky chart and your estimated Mars-Pollux and Mars-Regulus angular separation distances, use a compass to map Mars' position on the sky chart for each observation
In conclusion: Note and explain any patterns that emerge

3. Celestial Sphere Motion Observation:

Approximately 12 times during the Spring term, look at the asterism of the Big Dipper and the constellation Cassiopeia at different times of the night (10pm-5am) (Also, when available, look at the constellations of Auriga and Sagittarius.)

Draw their orientations in the sky referenced to the your horizon and your zenith for each of the observations
In conclusion: Note and explain any patterns that emerge

Observations and Reporting

The GSI will describe during your first discussion, how to carry out these observations.

We can't guarantee clear weather!! Thus:

Start soon -- don't leave this until late in the term
Be diligent -- try to observe frequently, so that you don't miss clear skies

Use a copy of the Observer's Notebook page at Projects to record each observation, and hand in these, together with a summary of your results/conclusions by the last day of classes. These are your personal observations; treat them seriously, and in particular

be careful to record the date, times, and your location.
