As a followup to my recent EO-1 post here another set of unusual images from this satellite from a few months ago.
These kind of show the start of the polar day in the 2016/2017 summer in the Antarctic. At these latitudes (about 77.5 degrees south) most of the year is either dark all day (polar night) or with permanent light (polar day). These images are from the short timespan in between when you actually have a sunrise and sunset. To be precise these actually all depict sunset with respect to the daily move of the sun but as a sequence they illustrate the end of the transit from polar night to polar day.
All these images show Mount Erebus on Ross Island with the Hut Point Peninsula where research stations from New Zealand and the United States are located.
