Unformatted text preview: AST 3722C Spring 2008 Lab 2 solutions Scoring: Mars part - 15 points Saturn part - 10 points Steps 2-7 for Mars: 2.5 points for each night, and must have 4 nights of observations, so total of 10. Step 9 for Mars: 5 points. Steps 2-7 for Saturn: 2.5 points for each night, having at least 2 nights of observations, so total of 5. Step 9 for Saturn: 5 points. 2. Sketch of [Mars/Saturn] and nearby stars. 3. Date, Time, LST, [Mars's/Saturn's] direction in sky. 4. Angular distances from [Mars/Saturn] to 3 stars. 5. Mark on sketch the names of stars and constellations. 6. Estimate [Mars's/Saturn's] RA and Dec. For your info, the ephemerides are below. The table gives the position of [Mars/Saturn] at 0200 UT on the day given -- which is 9pm EST (or 10pm in EDT) on the calendar day before. You can see that the RA and Dec don't change much over the course of a night. Also given is the azimuth and altitude, though of course they would change a lot over the course of a night and strongly depend on when you actually observed. Don't worry, I don't expect you to have many-digit accuracy on your RAs and Decs.
