What matters is your geomagnetic latitude, which measures where you are relative to the magnetic poles.
2.
The round-trip time varies with the geomagnetic latitude of the transmitter and is typically in the 140 300 ms range.
3.
In-flight experience showed that good data were obtained between 35?N and 35?S geomagnetic latitude outside the South Atlantic Anomaly.
4.
The four existing stations are latitudinally equi-spaced between 30?and 33?corrected geomagnetic latitude and cover the areas of Thessaly, Central Greece and the Peloponnese.
5.
This is somewhat surprising because the later, and less deep, Dalton sunspot minimum is clearly seen in auroral occurrence frequency, at least at lower geomagnetic latitudes.
6.
For example, the US Mark 6 magnetic pistol was designed and tested only once at 41?latitude ( 60?geomagnetic latitude ) at Narragansett Bay, but was primarily used in equatorial latitudes.
7.
Where r is the radial distance ( in earth radii ) to a point on the line, \ lambda is its geomagnetic latitude, and L is the L-shell of interest.
8.
The apparent duration at any particular location varied from 1, 200 to 10, 000 years depending on geomagnetic latitude and local effects of non-dipole components of the Earth's field during the transition.
9.
Because geomagnetic latitude is an important factor in auroral occurrence, ( lower-latitude aurorae requiring higher levels of solar-terrestrial activity ) it becomes important to allow for population migration and other factors that may have influenced the number of reliable auroral observers at a given magnetic latitude for the earlier dates.
