Greetings readers:
Ive had a look at several prediction programs to see
if I could find which was correct . I attach a specific
example and would appreciate if you could try your
favourite prediction program to see if there is any
agreement. Whilst the difference in the three programs
tried is not terrible it is more than my 2 degree field
of view will allow.
Time in all cases is South African Standard Time which is 2.0 hours
fast on UT. Angles in degrees.
Hope the spacing comes out okay - is okay in the text document
prepared offline but OUTLOOK EXPRESS seems to mess it up!
Ive left them as originally.
Ive always found GUIDE to be pretty good and I also have
confidence in Mikes program - my one is normally okay but none
of them agree.
Almost forgot - my coordinates needed !!
Longitude +18.51284 (East) Latitude -33.94058 ( south ) Alt=10
metres
Many thanks
Greg
