The clerke belt, or clark belt is the area of space above the earth's equator where the geo sats are placed. At a certain distance above the earth's equator, the speed of the geo sats are close to the speed of the earth equator. So that means the geo sats appear to stay above a certain area on the equator. On the equator if you go to the longitude of where the geo sat is placed it would appear overhead. The longitude of where the geo sat would be overhead is know as the orbital slot. For example if the geo sat has an orbital slot of 75 degrees west, that means on the earth equator if you where at 75 degres west, then the sat would be overhead . But as seen from other places on earth they apprear in a different part of the sky. For you the appear near -3 deg 38 min in declination, and aren't directly overhead. But they are higher in the sky for you then for me, as I am futher north in latitude. Enjoy the geo sat flares.

So look east in the evening and west in the morning. But whatis the 'Clerke Belt" and how do I find the dec for 21 N?
