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).
