Lab 2

Lab 2 has been posted on the course web site: http://www.astro.caltech.edu/~jrv/Ay20/labs/lab2_theAU.pdf. In this lab, you will use an image of Mercury's transit of the Sun, taken by the TRACE mission, to estimate the distance to the Sun. This builds on our measurement of the radius of the Earth (but feel free to use a more accurate value than the one we got). The lab is due Sunday night by midnight.
