No, if I specified a point in the celestial sphere (let's say RA 12h and Dec +10.0, then you could only stand on 10.0N latitude to have the celestial point go overhead. Let me clarify with a "bad" example: If the point in the stellar field is where Sirus is (RA: 6.75hr Dec.:-17.75deg) then you would have to stand on 17.75 South latitude and wait until 6.75hr RA was directly above (zenith). This will happen at slightly different times throughout the year - sometimes in darkness and sometimes in light. But there is one point in the stellar field that is always over it's corresponding point on earth (that is, a zenith to) in light (that is, with the sun less than 6 degrees below the horizon) for that point on earth. Where is the point in the sky (not on earth!)? - Jeff --- Tim Rogers <timrogers@charter.net> wrote: > Just for clarification, would this be true for any > location on the planet? > When you say "when observed from directly below on > the earth's surface," do > you mean *just* below the earth's surface > (centimeters or inches?) > > Tim Rogers > Sugar Hill, GA USA ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
