90.126 n 35.539


Where is that?


"90.126" n must be just past the North Pole, starting maybe from
Greenland (if 35.539 W) or Murmansk (if 35.539 E).


from *Astronomical Algorithms* (J Meuss, Willman - Bell,
2nd edition, p.93)

We cannot understand why the International Astronomical
Union, having first decided to measure all planetocentric
longitudes in the direction opposite to that of rotation, then
alters the system for the Earth (1982). We shall *not* follow
this IAU resolution and we shall consider *west* longitudes
as positive. This is in conformity with the longitude systems
on the other planets.

It's just a shorthand and I really do live in Arkansas - don't
rub it in.
