Explanation: Raise your arms if you see an aurora. With those instructions,
two nights went by with, well, clouds -- mostly. On the third night of
returning to same peaks, though, the sky not only cleared up but lit up with a
spectacular auroral display [4] . Arms went high in the air, patience and
experience paid off, and the creative featured image [5]  was captured as a
composite from three separate exposures. The setting is a summit of the
Austnesfjorden [6] fjord [7]  close to the town of Svolvear [8]  on the
Lofoten [9]  islands in northern Norway. The time was early 2014. Although our
Sun [10]  is nearing Solar Minimum [11]  and hence showing [12]  relatively
little surface activity, holes in the upper corona [13]  have provided some
nice auroral displays over the last few months [14] .
