PHYS UA 13

Observational : Fall 2011

General Information Classes. Lecture: Mon. 3:30–4:45, Room 102, Meyer. Labs: Mon. and Wed., 7:00–9:00, Room 224 Meyer. Later in the semester as the daylight hours change, we shall change the lab times to 6:20–8:20. You need to be registered for the lecture and one of the lab sections to be registered for the course.

Level. This course is a science elective. Pre-requisites are specified on Albert and in the CAS Bulletin.

Course Instructor. Patrick Huggins, Room 530 Meyer, [email protected]

Exams. There are weekly quizzes, a mid-term and a final.

Course Texts A Field Guide to the Stars and by Jay Pasachoff, 4th edition (Houghton Mifflin). The best handbook/field guide available. The Ever-Changing Sky by James Kaler, (CUP) paperback. Edmund Mag 5 Star Atlas (Edmund Scientific). An old publication but one of the best for actually identifying the stars.

Course Objectives Observational Astronomy is a course in technical amateur astronomy. The objectives are to learn which astronomical objects can be seen with the naked eye and small telescopes, when and where astronomical phenomena occur, and what is going on. The lectures provide the necessary background material, and lab sessions provide hands on observing activities with binoculars and telescopes when it is clear outside (about 50% of the time), and with maps, globes, and astronomical software when it is cloudy. Specific objectives include: the ability to identify bright stars and constellations; the use of astronomical atlases and handbooks; the ability to locate the planets; a firm understanding of sky coordinates, the seasons, the phases of the moon and eclipses; how to use astronomical telescopes and what can be seen with them. A detailed list of topics and the associated readings are given in the lecture/reading schedule. At the end of the course the successful student will likely be an informed and interested reader of the popular astronomical press such as Sky and Telescope and Astronomy magazines. Lecture Schedule
