i need the code in python to convert Geographic to Geomagnetic coordinates ?

Hi Amal,

You can use a Python wrapper for the AACGM-v2 C library, which allows converting between geographic and magnetic coordinates.

https://pypi.python.org/pypi/aacgmv2/1.0.13?

Hi Amal,

You could create a simple POST query to VITMO service (https://omniweb.gsfc.nasa.gov/vitmo/cgm_vitmo.html).

See https://github.com/Albom/utils/blob/master/geom.py

I tried Oleksandr's program with this result:

runfile('C:/WDC/geomag.py', wdir='C:/WDC')
