Dear Tony
Extreme latitudes are not extreme only when it comes to the climate and the
behavior of the sun. Using a compass to find geographical north at Longyearbyen
might be easier said than done. The alignment of the magnetic field at
Longyearbyen might vary during the day and from day to
Here's the site I use for magnetic declination values:

Hope this helps,

Tony, what website do you use for magnetic variation? I ask because I need
to know the MV for Oxford. I'm going to take my compass so that I can get
wall declinations of SGS in Oxford.
Have fun installing your new dial. Hope you get some sun.

The DoD World Magnetic Model predicts for 1 March 2004 at the given location a
magnetic declination of 4.06 degrees (compass will theoretically point
4.06 degrees to the east of true north). A different magnetic model,
the International Geomganetic Reference Field, gives 4.22 degrees. Take
your
I am sure you are well aware of the duration of sunlight at that time of the
year at that location (assuming the sun peeks through the clouds) but just
for your convenience, here is a graph of it.

Fellow Shadow Watchers,
Next week I will be setting off for Longyearbyen on
Spitsbergen in the Svalbard group of islands 500 miles north of Tromso to
install their new 24 hour stainless steel sundial. As any diallist is
painfully aware the most probable event for dial
