Named for the icy Canadian lake near Yellow-knife, Northwest Territories, where most of its images were taken, Prelude Lake by Bryan Rich White (Nitescapes 3-D, 2008, $64.95) is a lavish book containing 72 stereo image pairs of auroras plus two more of Comet HaleBopp. You view them with an included plastic "fuser," whose molded lenses perform almost as well as the glass ones of an antique stereoscope.
"Using this velocity and the nucleus's rotation period of about 9 hours, which was determined by astronomers at Vainu Bappu Observatory in Kavalur, India," explains Nolan, "we can say that Machholz's nucleus must be at least 1.7 km in diameter, if we were looking along its equator, or perhaps wider if we were looking at higher latitudes." (See www.naic.edu/pradar/ comets/C2004Q2.) By comparison, the nucleus of Halley measures approximately 16 by 8 km (see page 42) while that of HaleBopp is probably about 60 to 80 km across.
