1 ISP205L Spring 2006 Supplementary Instructions for SkyGazer Homework Assignments Updated: 3/23/06 Use these instructions along with the regular instructions found in Astronomy Media Workbook, Fourth Edition , by Micheal C. LoPresto. You will not get the right answers for many of the homework questions unless you follow these special instructions. Unless you are specifically told otherwise in the instructions given here, always do all parts of the exercises as described in the Media Workbook, and answer all of the questions in the Results Sheet at the end of each exercise. Tear out and turn in the Results Sheet. You do not need to answer the multiple choice questions or do the open-ended activity. All homework assignments are due at the start of class. Assignments turned in after that time will receive only half credit. Always print ( very legibly) at the top of each homework page your MSU Net ID. That is the part of your MSU email address that comes before the “@msu.edu”, and is the code that Angel uses to keep track of your work. Week 1 assignment, due week 3. SkyGazer Activity 1: Introducing SkyGazer. For part 2, set your location to Lansing, and set the time/date to 10:00 PM Standard Time, January 10, 2006. Week 2 assignment, due week 3. SkyGazer Activity 2: Motions of the Stars Do only Parts 1 and 2. Before beginning Part 1, use the list of cities in Control | Set Location to set your location to Lansing. SkyGazer Activity 3: The Celestial Sphere Do only Parts 1 and 3. Skip Parts 2 and 4. Even though you were using the same Three Cities exercise for SG2, it is easiest to just to start over again by going back to File | Open Settings | Basics | Three Cities. Set your location to Lansing, and the time to 9PM. In Part 1, you can easily find most of the stars on the sky chart by clicking on View | The Brightest Stars, and then on the star name. Markab is in the constellation Pegasus. Not all of these stars are above the horizon. Part 3 is important, but many people (including your professor) find the wording to be confusing. You should notice that some reference lines and points move along with you as you change location, and therefore always look the same as seen on the sky chart. Others stay fixed relative to the stars and therefore seem to move along with the stars as you change location. You are asked to circle the lines and points that move along with the stars as you change location. After the list of lines and points for you to circle, the last section of text should really have said: “The reference markers that move along with the stars (i.e. are fixed relative to the stars) as you change location are part of the EQUATORIAL | ALTAZIMUTH (circle one) coordinate system. Those that do not move
