Welcome to the AST 111 Lab: Astronomy Lab I for Fall 2025!

Please stand by for last minute notices on changes to the class rules and schedule as required by ASU. The AST 111 Labs in Fall 2025 are in person. Zoom may be used for some of our office hours, as indicated on the Contacts page.

Course Overview: This Lab will familiarize you with basic concepts of astronomical observations: the night sky, the Moon, solar system planets and extrasolar planets.

Learning Outcomes: Understand and be able to use basic concepts of astronomical observations, the night sky, its constellations and their daily and seasonal motion, astronomical telescopes, and develop a basic understanding of the Moon, Mars, and planets in the outer solar system, as well as nearby exoplanets.

There are 4 types of lab exercises to be done: Naked-eye based, Telescope-based, Computer/Instrument-based, and Planetary data based. You will meet on the SAME day every week. Please check the Schedule button on the left for the room where your section will meet each week, whether your section will start at 3:30 or 7:30 pm in any given week. This schedule is TENTATIVE, since both the room number, the starting time and the Lab assigned to your section each week schedule may change throughout the semester, depending on weather and TA schedules. Attendance will be taken at the start of each Lab section, so please arrive on time.

There is no lab manual to purchase for this course. Click on Syllabus to see the simple items you will need to buy for this Lab. Click on Schedule to see which Labs exercises you will do each week. You are expected to download these Lab Scripts each week, print them out, and bring a paper copy to class to do the exercise. Click on Contacts to get in touch with your TA if you have questions.

There are several requirements for this class: you need to make sure you have web access - the University has provided ample access to computers across campus and throughout the residence halls to print your Labs. Second, you need to check your ASU email address regularly (daily), since this is the primary mechanism that your TA will use to contact you. (Canvas cannot send Emails to non-ASU Email addresses). If you have a problem with these policies, you need to see the Instructor for the class: Prof. Rogier Windhorst (see Contacts page).

There are NO AST LABS during the FIRST week of classes on the ASU Tempe campus: Th Aug. 21. ALL AST Labs on the ASU Tempe campus START the SECOND week of the semester on Monday Aug. 25-Thursday Aug. 28, 2025.

Labor Day (Monday Sept. 2) and Thanksgiving (Th Nov. 28) are holidays, so there are NO Labs those days, nor on Wed Nov. 27. The University has Fall break Mo-Tu Oct 13-14 in 2025. All Labs sections will do a minimum of 12 Labs + the Game of Science Lab during the semester (see Schedule page).
