eclipse times

Laren Dart Mar 6, 2006

When the time of an eclipse is found via "Conjunction finding" then viewed
on the eclipse map, the times are different. I seem to recall that one time
is the actual viewing time at the site, and one is the time of maximum
magnitude along the eclipse path.

Example: A total eclipse occured at Babylon (Al Hillah, Iraq) in 136 B.C.
Setting start time at Jan 1 -135, 00:00 LMT, "Conjunction finding" gives a
time of 08:31 local time. Switching to the geo map gives a time of 09:11
local time. I believe "Conjunction finding" gives the time and aspect of
the eclipse at the location entered in Settings|Location, and geo map time
is for maximum magnitude along the eclipse path.

I'm pretty sure this is correct, but would appreciate someone confirming it.

Thanks,
Laren
