Calc Magnetic Local Time: UT & Geo Lat/Long

[erotavlas]

Does anyone know how to calculate Magnetic Local Time for a position on earth, given the current Universal Time, and the position in Geomagnetic latitude/longitude?

At night, when you and your nearest magnetic pole and the Sun are on the same plane, you are at local magnetic midnight. From that point in time you measure local magnetic time in the normal manner of one hour per 15° of longitude.

Yes, I do! The formula for calculating Magnetic Local Time (MLT) is:

MLT = UT + (Longitude / 15) + (Magnetic Longitude / 15)

Where:
- UT is the current Universal Time in hours
- Longitude is the position in longitude in degrees
- Magnetic Longitude is the position in geomagnetic longitude in degrees

So for example, if the current UT is 10:00 AM, the longitude is -75 degrees, and the magnetic longitude is -80 degrees, the MLT would be:

MLT = 10 + (-75 / 15) + (-80 / 15) = 10 + (-5) + (-5.33) = 10 - 10.33 = -0.33 hours

This means that the Magnetic Local Time for this position would be 12:00 AM (midnight).

Hope this helps! Let me know if you have any other questions.
