The NyAlesund SGO

http://siempre.arcus.org/4DACTION/wi_alias_fsDrawPage/1/107

is some distance North of Longyearbyen (how many places can say  
that ?), and I used to have
a nice picture, which alas I cannot find, of the satellite link (not  
the 20 meter dish in the picture) apparently pointing at the mountains.

It does indeed have fiber now, and has been used for eVLBI
