Equinox label correction

Since the planets orbit counterclockwise as seen from above our north pole, interchange "2006 equinox" with "1965 equinox" on Figure 14-3.

IR Photo of Uranus

An infrared image taken at Mauna Kea on September 10/11, 1994, by Keith S. Noll, Diane Gilmore and David R. Soderblom at the NASA Infrared Telescope Facility. Filters between 1.2 and 2.2 microns were used. The images were taken with a 256x256 pixel infrared array called NSFCAM. The images appeared in Sky & Telescope for March 1995, p. 12.

At this infrared wavelength, Uranus's rings show clearly though they are unresolved from each other. Ariel is at upper left and Miranda is at lower left. On Uranus, which was only 3.7 arc sec across, the offset of the south-pole's haze is visible.
