Back on May 26, when I flew from Washington, DC, to Geneva, Switzerland, the final rays of sunset lit the western horizon equally nosotros passed over Nova Scotia; past times the fourth dimension nosotros reached Newfoundland, it was totally dark. Within approximately other hour, however, equally nosotros flew eastward to a higher house the North Atlantic, the glow of "sunrise" spread across the northern horizon too persisted until nosotros angled southeastward toward the coast of Ireland; past times then, the eastern sunrise had begun to illuminate the landscape.
That "northern sunrise" was, of course, the southern extent of the perpetual daylight that occurs to a higher house the Arctic Circle during the calendar month preceding too the calendar month next the summertime solstice. The contestation of the Earth's axis produces this annual phenomenon also equally the perpetual darkness surrounding the wintertime solstice.
As alongside close natural spectacles, it was a affair of beingness inwards the correct house (i.e. latitude) at the correct time. Had nosotros crossed the Atlantic further south, I would non accept seen the "northern sunrise."
