About 1,800 km north-east of New Guinea, it is located mid-ocean at 7 degrees North latitude, and is part of Chuuk State within the Federated States of Micronesia. The atoll consists of a protective reef, 225 km around, enclosing a natural harbour 79 x , with an area of 2,130 sqkm .

Context_2 : Operation "I-Go" (い号作戦 , I-Go sakusen ) was an aerial counter-offensive launched by Imperial Japanese forces against Allied forces during the Solomon Islands and New Guinea Campaigns in the Pacific Theater of World War II from 1–16 April 1943. In the operation, Japanese aircraft—primarily from Imperial Japanese Navy units under the command of Admirals Isoroku Yamamoto and Jinichi Kusaka—attacked Allied ships, aircraft, and land installations in the southeast Solomon Islands and New Guinea. The goal of the operation was to halt the Allied offensives in New Guinea and the Solomons and to give Japan time to prepare a new set of defenses in response to recent defeats to the Allies in the Battle of Guadalcanal and in New Guinea at Buna–Gona, Wau, and the Bismarck Sea. Context_3 : The Battle of Hollandia (code-named Operation Reckless) was an engagement between American and Japanese forces during World War II. It took place in spring of 1944 and was part of the New Guinea campaign. The landings were undertaken simultaneously with the amphibious landings at Aitape ("Operation Persecution") to the east. The battle was an unqualified success for the US forces, resulting in a withdrawal by the Japanese to a new strategic defence line in the west of New Guinea and the abandonment of all positions in the east of the island. Context_4 : Asterophrys turpicola (common name: New Guinea bush frog) is a species of frog in the family Microhylidae. It is widespread in New Guinea and found in both West Papua (Indonesia) and Papua New Guinea, although it appears to be absent from the eastern half of Papua New Guinea. It also occurs on the island of Yapen, off the north-western coast of New Guinea. The species is known for its aggressive behaviour: it can attack and bite viciously. Context_5 : Operation Inmate was an attack by the British Pacific Fleet against Japanese positions on Truk Atoll in the central Pacific Ocean during the Second World War. The attacks against the lightly defended islands on 14 and 15 June 1945 were conducted to provide combat experience for the aircraft carrier HMS "Implacable" and several of the fleet's cruisers and destroyers ahead of their involvement in more demanding operations off Japan. Context_6 : The Papua New Guinea Defence Force (PNGDF) is the military organisation responsible for the defence of Papua New Guinea. It originated from the Australian Army land forces of the territory of Papua New Guinea before independence, coming into being in January 1973 and having its antecedents in the Pacific Islands Regiment. The PNGDF is a small force numbering around 2,500 personnel and consists of a Land Element, an Air Element and a Maritime Element. It is a joint force tasked with defending Papua New Guinea and its territories against external attack, as well as having secondary functions including national-building and internal security tasks. Context_7 : A total solar eclipse occurred on February 5, 1962. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Totality was visible from Indonesia, Netherlands New Guinea (now belonging to Indonesia), the Territory of Papua New Guinea (today's Papua New Guinea), British Solomon Islands (today's Solomon Islands), and Palmyra Atoll. Context_8 : The Hagen Mountains (German: "Hagengebirge" ) are a mountain range over 3,000 metres high in Papua-New Guinea, in the northeast of the island of New Guinea. The range lies on the territory of the former German colony of German New Guinea in the Kaiser-Wilhelmsland, west of and parallel to the middle Ramu valley. It was discovered in 1896 and named after Curt von Hagen, then director general ("Generaldirektor") of the New Guinea Company and governor of German New Guinea. Curt von Hagen's father was the royal adjutant and lieutenant-general, Heinrich von Hagen; Curt von Hagen was thus a great grandson of the polymath, Karl Gottfried Hagen, of Königsberg.

The other OEF mission in Africa is known as Operation Enduring Freedom – Trans Sahara (OEF-TS), which, until the creation of the new United States Africa Command, was run from the United States European Command. fact_1 : Operation Inmate was an attack by the British Pacific Fleet against Japanese positions on Truk Atoll in the central Pacific Ocean during the Second World War. fact_2 : Chuuk Lagoon, previously Truk Lagoon, is a sheltered body of water in the central Pacific. fact_3 :  About 1,800 km north-east of New Guinea, it is located mid-ocean at 7 degrees North latitude, and is part of Chuuk State within the Federated States of Micronesia. Question: Operation Inmate was an attack that took place on the atoll that is how far northeast of New Guinea?
