Class time and place:
Weekly meeting at 108A Sci Annex (Astro Lab): Wednesday 3:00 pm.
Default observing time: Mon, about 8:30-9:45 pm (will shift later as seasons change).
Backup observing: Wed, about 8:30-9:45 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.)
(The place for any additions.)
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.
Astronomy labs requiring math at the algebra level. These labs will reinforce the material presented in the Stars and Galaxies class (PHYS 1061), including: the celestial sphere, coordinate systems, proper motions of stars, the HR Diagram, Cepheid stars, Galaxy rotation and the Hubble Law. 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.

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.
Attendance is essential for the night time lab sessions. It is nearly impossible to "make up" a data gathering session since good observing conditions are so rare. The Monday meeting is also important to intend, but you may be able to obtain the information by communicating with me (by email or in a special meeting). Let me know as soon as possible when you know you will have to miss a lab.
Calculators. I encourage you to have a calculator in this lab.
Notebooks . You need a notebook for this lab. Preferably one which allows you to remove paper without frills.

Telescope Certification and Sky Quiz:
You can be "certified" to operate our goto telescopes. First, you need
to understand how coordinate systems work (RA and Declination,
Alt and Azimuth, NCP, celestial equator, ecliptic). Then you
need to know the basics of operating the goto telescopes
(currently on Celestron CGPro mounts). You should be able to
start up the telescope, track down objects that are too faint
to see with the naked eye, and then safely shut down the telescope.
The Sky Quiz will also require you to identify constellations
(at least 7) and bright stars and planets (at least 5).
If we can't get nights during the last 2-3 weeks,
this may be dropped as a requirement.
Doing indoor labs: the indoor labs
are usually computer-based. Therefore, you will have the option
to work on your lab at any time. You will be shown the 3-4
computers that have "Virtual Astronomy Labs" installed on the first
I will also try to give you important astronomical background and
context for each VAL lab.
Your completed lab should include: 1) tables of data (with units
and clear column headings), 2) Your name and date, 3) answers to
all questions posed in the VAL lab, 4) answers to any other question
posed by your instructor, 5) graphs of data, if important for
answering the questions. I encourage you to use Excel
or Libreoffice to create your data tables and graphs.
Obtain a key from Cyndy Harris or Megan Morris in the STM office on the 1st floor of Meyer (Me 165).
Doing Outdoor labs: You will typically receive a worksheet during the Monday meeting or at the nighttime session. Do your best to neatly fill these out. (It's not easy in the cold and dark.) Use a clipboard and clip-on light stored near the observatory's entrance. You may need to take the sheet home in order to complete the questions and neaten things up. For some labs, I will probably need to provide you with hardcopies of images/data we take at the observatory. You can staple these to your final lab. 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.
First Lab (weeks 1-3): We will start with "Planning an Observing Run", a lab designed to introduce you to star maps (including field guides and planetarium programs). You will use field guides or other star maps with labelled objects to find interesting an interesting class of objects to observe with a small telescope. Choose a theme, like "globular clusters". You will then write out a detailed schedule as if you will be observing your objects for a 4 hour period during the second month of the semester. In fact, we will allot at least 10 minutes to just one of your objects. The observation will most likely be a CCD or digital camera observation, but could also involve an eyepiece viewing. You must be sure that your object will be accessible at the scheduled time!
