Hipparchus (and possibly Aristarchus before him) also derived the Moon's distance from the duration of a lunar eclipse . Because the Earth casts a much larger shadow than the Moon, such an eclipse usually darkens the entire Moon, for several hours. ... If the Sun is assumed to be very distant, and if the Moon crosses the middle of the shadow (if not, corrections must be made), the width of the shadow is expected to be about 2r , twice the Earth's radius r . ...

Information about this camera is below . ... Yes , I did in fact put on the web one of the earliest web cameras ever. I can document the software as early as May 1994 (based both on backup tapes, as well as the May 1994 annular eclipse which we imaged using one of these cameras), although I'm sure I had things working over the winter before that. I can't remember if my inspiration was that someone else put a camera on the web, or that someone else had a camera on the Mbone in their office. ...
