Virtually anywhere in the northern latitudes is a site for
the sight. They are not uncommon phenomena in Scotland
and N.E.England...there, Iv'e saved you the cost of a trip to Finland or Alaska.
As a kiddie living in the N.E. we occasionally saw them on bitterly cold, cloudless ,moonless nights in winter, My mother brought us indoors, 'cos she considered them to be an omen of v. bad luck .
Years later, on investigation, I found the source of this superstition; seemingly it comes from the poem 'After Flodden' and goes;
'And all night long the northern streamers
Shot across the trembling sky;
Fearful lights which never beckon,
Save when kings and heroes die '
