Hi Everyone,
I'm looking for help calculating Magnetic Local Time. I have experience
with magnetic lat/lon coordinate systems (specifically, CGM), but not MLT.
If anyone can give me some assistance, code, URL's or other resources, I
would be grateful.
Thanks,
-k.

I have a DLM for UNIX which implements IGRF and the NSSCDC GEOCGM library.
One of the parameters caclulated by GEOCGM is the UT of MLT midnight.
See http://nssdc.gsfc.nasa.gov/space/cgm/cgm.html for details.
If you are interested I could probably package this up for you with some
basic installation instructions.

Hi Ken,
i got only f77 code for deriving the 'Magnetic Universal Time'. please
contact me, if you are interested.

Try the routines at <ftp://cdaweb.gsfc.nasa.gov/pub/CDAWlib/source/>,
particularly geopack.pro. The routines eccmlt.pro and mlt.pro call Fortran
routines in <ftp://cdaweb.gsfc.nasa.gov/pub/CDAWlib/radar/>
