Converting from Classical to Robotic Astronomy: The Lowell Observatory 0.8-m Telescope

Figure 4

Lightcurve of Pluto in March-July 2000. The rotation period of Pluto is roughly 6.4 days and requires many nights to obtain a complete lightcurve. The points with error bars are the result of 35 nights of observation and nearly 1000 individual images. The solid curve is a 4-term fourier series fit to the lightcurve. For comparison the lightcurve from 1986 is shown (dashed line).
