	Hi all!

	Does anybody have some accurate (+/- 1 minute) data for the following:

		* Solar eclipses
		* Lunar eclipses
		* Apogees and perigees of the moon

	I have implemented some of the formulae in Jean Meeus book,
	"Astronomical Algorithms". His formulae for perigee gives a maximum
	error of 31 minutes (mean error 3 minutes) for the perigees of
	1987-2022 and I would like to see how much better I can make it.
	Pointers to tables of accurate data would be much appreciated.

	Also, if you have any information on algorithms to calculate more
	data on lunar and solar eclipses. The data I would like to be able
	to calculate is for example as given in this excerpt from a Swedish
	almanac:

	"Partial solar eclipse of Nov 13, 1993: Starts at 19.46 GMT,
	 138 degrees 2 minutes East, 31 degrees 17 minutes South and ends
	 at 23.43 GMT, 67 degrees 45 minutes West, 48 degrees 44 minutes
	 South. Maximum accurs at 21.45 GMT when it is 93% of the Sun's
	 diameter."

	Please reply by e-mail.
