Drönarattack 40 mil från Sverige – Kristersson och Finlands president har hörts

Norra polcirkeln eller arktiska cirkeln är en parallellcirkel på jorden som motsvarar den linje som avbildas genom skärningen av normalen till ekliptikalplanet genom jordens medelpunkt med jordytan under jordens rotation på norra halvklotet (den "yttersta plats" – räknat från Nordpolen – där solen inte "går ner" vid sommarsolståndet samt inte "går upp" vid vintersolståndet). Norra polcirkeln ligger på cirka 66˚ 34' N. På grund av variationer hos jordaxelns lutning, vilken varierar under en period på ungefär 41 000 år mellan 22°2′33″ och 24°30′16″ , och som på kortare sikt varierar även med precessionen och nutationen, flyttar sig polcirklarna kontinuerligt, för närvarande med cirka femton meter norrut per år (ca. en bågminut på tolv år). Därtill kommer att polrörelsen gör att breddgraderna flyttar sig, om än långsamt, relativt landytan. På himmelssfären finns också en motsvarighet med samma namn i form av den lillcirkel som går genom den nordligaste punkt som solen når på himlen.

Olenya (also Olenegorsk) has been a major Russian Navy reconnaissance base, located on the Kola Peninsula 92 km south of Murmansk. As of 2020, units at the base are subordinate to the Long-Range Aviation branch of the Russian Aerospace Forces. The base and its staff settlement (Vysoky, Murmansk Oblast), across Lake Permusozero from the city of Olenegorsk, are served by the Olenegorsk rail station (formerly Olenya station). Olenya has served as the headquarters for 5 MRAD (Naval Reconnaissance Air Division), and has hosted two reconnaissance regiments. Its 3500-meter runway is the longest on the Kola Peninsula, making it a key facility for intercontinental flights across the North Atlantic basin. The base is home to the 40th Composite Aviation Regiment as part of the 22nd Guards Heavy Bomber Aviation Division. Olenya was first detected by US intelligence in 1957, and was listed as having a runway length of 3350 m (11,000 ft). The base served as a forward deployment field for Long Range Aviation and was one of nine Arctic staging facilities for nuclear strikes on the United States. An analysis in 1966 revealed 21 Tupolev Tu-16 Badger aircraft. Near the airfield is the Olenegorsk Radar Station ballistic missile early warning site, which entered service in 1971. A number of surface-to-air missile sites were operational near Olenya during the Cold War. During the 1960s and 1970s, Olenya was used as a refueling stop on the Moscow to Havana Tupolev Tu-114 route. As of 2006, Google Earth imagery showed nearly 40 Tupolev Tu-22M bombers on the airfield, but by 2018 only four of the aircraft appeared serviceable with another 27 aircraft awaiting disposal. On 7 October 2022, satellite photos showed 7 Tu-160 and 4 Tu-95 at the air base.
