Welcome to CSUF's Astronomy 101

These lecture notes and tutorials correspond to the asynchronous online version of ASTR101 at California State University Fullerton.

The Modules include online notes for each recorded lecture presentations, with "in-class" questions. There are also questions-only versions to use with the recorded lectures.

The Activities go through questions to check your understanding, activities to work through to practice applying these ideas, and discussion topics for your group. Many of activities follow "Lecture-Tutorials for Introductory Astronomy", by Ed Prather, Jeff Adams, Tim Slater, and Gina Brissenden.
