Abstract:
For the epochs 1942.0, 1960.0, 1990.4 the normal geomagnetic field (N.G.F .) in the form of a first order polynomial in latitude and longitude, is computed and its mean secular variation is found. The field secular variation is also computed according to I.G.R.F. The N.G.F. and I.G.R.F. over Albania are compared.
