Gone to See Europe. Semester at Sea Spring 2013 Enrichment Voyage on the MV Explorer. Day 45: At Sea between Stockholm and Copenhagen.
Late night or early in the morning (hard to tell this far north when there isn’t much darkness at night) I looked out my cabin window on the MV Explorer and saw the electric blue Noctilucent clouds. I read about them before (http://www.spaceweather.com/), but had never seen them. The clouds are ice crystals that are very high that you can only see for a short time when the sun is below the horizon. One theory is the crystals are nucleated when micro-meteors pass through the upper atmosphere. We were in the Baltic Sea traveling from Stockholm to Copenhagen and the sun doesn’t set until very late I set up a camera in my cabin and and started taking pictures.(Nikon D4 camera, 28 mm f/1.8 lens (ISO 200 or 800, 28 mm, f/1.8, 1 sec)).
