Laboratory Codes, Times, and Instructors
80316 Tues, Thurs 12:30-1:50 PM Dunn
Meeting Place: Always meet in Room ST-2 at 12:30 P.M. SHARP on class days for lab activities. It is important to show up on time to receive handouts and hear important announcements.
Photo/imaging Sessions: Only students in Astronomy 14 may attend the sessions. Always dress warmly for outdoor activities and if possible bring a red flashlight. Check with your instructor for the status of scheduled sessions. We will meet on selected THURSDAY nights.
Break Period: There is no formal break period during class. When taking a break from class activities, students are expected to use common sense on when to take a break and to inform their team members when doing so.

If you decide to drop the class, please drop before the deadlines. Instructors may drop a student for excessive absences and, then again, they might not.
CHECK YOUR SCHEDULE OF CLASSES FOR THE DEADLINE DROP DATE ....
…. Hopefully, you WON'T drop the class ...
Grading and Attendance
1. The final grade in this class is based on total "assigned" points (roughly 320 points):
A = 90% or more of total points assigned
B = 80% or more, but less than 90%, of total points assigned
C = 70% or more, but less than 80%, of total points assigned
D = 60% or more, but less than 70%, of total points assigned
1) Completing the exercise and the corresponding exercise sheet.
2) Completing questions and putting them on an “Observer’s Summary of Activity” sheet in the Astrophotography Log.
General Instructor Expectations of Students: We expect each student to give his or her best effort in participating in class activities and accomplishing assigned tasks. We expect students to adhere to their behavior responsibilities as detailed in the Sierra College Student Handbook. Cheating, plagiarism, or any other forms of dishonesty are considered grounds for an immediate course grade of F and possible dismissal from Sierra College.
Student Expectations of Instructor: You can expect our best effort in teaching the principles of Astronomy. We hope to impart in our students a sense of excitement in observing and studying nature’s show in the cosmos. We are very open to suggestions for topics that students wish to discuss or improvements in the course content and/or presentation.
Student Safety: All students should be aware of the proper procedures under emergency conditions in the classroom or building. This awareness includes how and where to meet during an evacuation, and location and use of the building first aid kit, fire extinguishers, and phones.
COMPLETE THE GREY INFORMATION CARD
Give this card to the instructor before leaving class on the first day. The small square in the upper right hand corner of the card is used for your group/telescope letter. Your instructor will assign this letter to you.
Thank you for electing to take Astronomy 14. I hope you will learn much and enjoy the subject as much as I do. David Dunn
Our class will be observing on 5 of these dates. These dates are dependent on weather/sky conditions! Confirmation of going will be in class or on the Astronomy 14 Canvas Website.
