[quote:TBar1984:MV8xNTQ1NjE4XzI1NTI2OTI3X0EyQTg2QzIx] [quote:Anonymous Coward 1447243] im at only the 3 minute mark and he has said that the time on the webcam clocks is wrong a couple times already. so in order to believe what he has to say over the full 25 minutes is predicated on the webcam time being off? i dunno man... on the fence [/quote] Actually the time on the webcam has absolutely no impact on the geographic location of the base or the sun. That should be obvious. No matter what time they stick on the cam, the base is still located at 67°36' S 62°52' E, the sun's declination is still 23°21.8' N, and meridian passage for 60° E is still 12:03 Zone Time. The Nautical Almanac and my program both use the geographic time, which for Mawson is GMT +4. [/quote]

Here you go, blow by blow calculations of where the Celestial & Visible horizons are located. Suntard Doom Finally Cured.
From The American Practical Navigator, "For any elevation above the surface, the celestial horizon is usually above the geometrical and visible horizons, the difference increasing as elevation increases. It is thus possible to observe a body which is above the visible horizon but below the celestial horizon. That is, the body’s altitude is negative and its zenith distance is greater than 90°.
