Sunset in the Arctic (2017) c. Jules Mitchell.

 The light in Tromso is incredible, especially when the sun starts to return. Sunsets appear and disappear and then reappear for what seems like hours.

Unlike the tropics where you sit drinking a gin and tonic waiting for the green flash. We were lucky to see three flashes, two in The Bahamas and one on Grand Cayman. As a heads up, they are not really flashes but a pulse of green light which is a bit of a surprise.
