Class time and place: 
     Weekly meeting at 108A Sci Annex (Astro Lab): Monday 1:00 pm.
     Default observing time: Mon, about 8-9:15 pm (will shift later as seasons change).
     Backup observing: Wed, about 8-9:15 pm.
We will try to observe once per week, but clouds inevitably interfere.
We use the Weekly meeting to assign new indoor and outdoor labs, turn in labs, and go over labs. (Every other Wednesday, the Astronomy Club meets at 9 pm, so Wednesday will not always work as a backup.)

Lab on Proper Motion.


This is the lab associated with introductory astronomy course Physics 1061, "Stars and Galaxies". There is only 1 section, since only astronomy minors (or physics majors with astronomy concentrations) really have to take this lab. You will have an informational meeting with me on the second week where you will be assigned your first lab.

Textbook and Notebook: No textbook is required. (Handouts will be provided for some labs while others will be computer-based.) However, you should have a notebook for the lab. Use it to record notes on our weekly meetings, and to write out a description of the computer-based labs.

Course Description:
Astronomy labs requiring math at the algebra level. The course combines indoor, computer based labs with observing sessions at the ONU Observatory. The outdoor sessions intend to give you practice in finding your way in the night sky, and also give you experience in using telescopes and CCD detectors for imaging.

Here is a link to the ONU Observatory web site (including maps):


Telescope & sky quiz Telescope & sky quiz 5%
Labs Indoor and outdoor labs (see schedule) 95%

Your final letter grade is calculated roughly as follows:


I will not grade any "harder" than the above. 
Grading is based primarily on completion of the required indoor and outdoor labs. The labs are worth between 5 and 20 points, depending on how much work is required to complete them. A 1-week indoor lab is worth about the same as a 1-week outdoor lab. Most labs will be graded with a "quality control" mindset in which I ask you to redo parts in order to get full points. Some may just be returned with deductions for missed steps or doing things wrong. I like to see thoroughly done labs.

Course Policies

Attendance  is essential for labs.

Quizzes may be given occasionally.  They will consist of multiple choice/short answer questions.

Calculators. I encourage you to have a calculator in this lab.

* First unit number is for Ver. 2, second unit number is for Ver. 3.

Independent stargazing:  the goal here is to become familiar with the night sky. (If you ever find yourself in an astronomy graduate program, you will probably have to find planets and constellations for undergraduates.)  Practice learning the constellations on your own during non-lab nights.  You can also learn constellations with a computer planetarium program, but a flat computer screen does not truly represent a sky that wraps around you.  Practice up for the ...

Telescope certification or Constellation quiz:  be able to point out 7 constellations, and the 5 brightest objects (stars or planets) visible.  Be able to find the north celestial pole, the zenith, and the celestial equator.  If we don't get a clear night during the last 2 weeks, I will test you using a planetarium program.

Doing labs: the indoor labs are usually computer-based.  Therefore, you will have the option to complete the lab at any time, not just the usual meeting time.  However, you should be present at the begining of the class period to get instructions.  (The above schedule is VERY subject to change.) I also hope to take you out when weather conditions are good.  In general, if the weather is good (<20% cloud cover, >20 deg F) we will go out.

Plan an "observing run": use star maps, a celestial sphere, or a planetarium program to find interesting objects to observe with a small (~5-inch) telescope.  Write out a detailed schedule so that you can observe for about 1-2 hours on a clear night during this quarter.  You must be sure that your object will be accessible at the scheduled time!
