Stargazing in Anchorage, US
Anchorage's extreme latitude (61°N) means summer brings perpetual twilight — the sun barely sets around the solstice, and astronomical darkness doesn't return until August. From September through March, however, the long nights, low humidity, and clean Arctic air produce exceptional conditions. Aurora is a headline attraction: Anchorage sits under the auroral oval, and displays are frequent from September to April. Bortle 4–5 in the city drops to Bortle 2 within 30 minutes on the Kenai Peninsula.
