Corrections
Some corrections are in individual lab guides in the Instructor’s Notes, and we provide an updated list here.
L17: Rotation of the Sun
Last page of the lab should read “Use a different color to label 0° longitude on the Sun for this second position of the Earth.”
The last image of the Sun is from the wrong date: find a 20 May 2013 image here.
L32: Spiral Arms & Star Formation
- Pinwheel illustration should have different patterns on each quadrant (students can add this themselves).
