The southern lights are a common display over Antarctica during the continent’s winter. It would probably be really neat to see them from Halley IV, but for the past six years, the research station has been kept empty during winter out of caution, “because of the complex and unpredictable glaciological situation.” If the station were to float off into the sea, a rescue would be much more challenging in the 24-hour dark and brutal weather than in the summer months.
