Local Magnetic Time

AI Thread Summary

To calculate Magnetic Local Time (MLT) for a specific position on Earth, the current Universal Time (UT) and the geomagnetic latitude and longitude are required. MLT is determined based on the relationship between the observer's location, the nearest magnetic pole, and the Sun's position. At local magnetic midnight, when the observer and the nearest magnetic pole are aligned with the Sun, MLT can be measured. The standard method for measuring MLT involves calculating one hour for every 15° of longitude from this midnight point.

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.

Thread 'Landslide, tsunami, seiche in Tracy Arm fjord, Alaska - 10 August 2025'

On August 10, 2025, there was a massive landslide on the eastern side of Tracy Arm fjord. Although some sources mention 1000 ft tsunami, that height represents the run-up on the sides of the fjord. Technically it was a seiche.

Thread 'Could an external cosmic body have influenced Earth’s geology?'

Hello, I’m currently writing a series of essays on Pangaea, continental drift, and Earth’s geological cycles. While working on my research, I’ve come across some inconsistencies in the existing theories — for example, why the main pressure seems to have been concentrated in the northern polar regions. So I’m curious: is there any data or evidence suggesting that an external cosmic body (an asteroid, comet, or another massive object) could have influenced Earth’s geology in the distant...
