In 1940, the High Altitude Observatory (HAO) was established in 1940 in Climax, Colorado, by Walter Orr Roberts and Donald Menzel. It was associated with both Harvard College Observatory and the University of Colorado and was incorporated in 1946. At the time it was

180-596: A conventional strike force in Europe, the 366th Tactical Fighter Wing moved to Holloman. The move was a result of French president Charles DeGaulle 's deep suspicion of "supranational organizations" and his country's shift away from the NATO orbit in the early 1960s that ultimately led to the closure of American air bases in France . 366th TFW was organized as follows: At the time of the wing's arrival at Holloman, they flew

240-556: A diverse range of native flora and fauna including more than 200 species of birds, as well as mule deer. It was named after the presence of the National Solar Observatory on Sacramento Peak , in a vote that was allegedly rigged by the observatory's director John Evans . The road leading to Sunspot from Cloudcroft is New Mexico State Road 6563 , named for the brightest wavelength of hydrogen emission , H-alpha . This scenic byway features signposts marking

In all, F-117 pilots flew more than 80 missions and dropped nearly 100 enhanced guided bomb units against key targets. Approximately 300 people deployed with the air package and provided direct support to the F-117 mission. Additionally, hundreds of other 49th FW personnel were deployed on other missions. The 479th TTW

480-442: A result, solar observations "became essential to the war effort". Suddenly the field of solar astronomy became an appealing goal for both astronomers and the military. The Sacramento Peak Observatory was conceived as a complementary telescope to the existing facilities in Climax, as Roberts had realized that "there were long periods of cloudiness, especially during the winter, when it was not possible to make observations", and hence

540-584: A second dedicated solar observatory should be established. The practical applications for solar research, as discovered by the military during World War II, regarding the impact solar activity had on radio communication spurred the US Congress to provide for a military-funded observatory. It became an important mission of the USAF to establish a solar observatory and "after the war, when the Air Force recognized

1920-603: The U.S. Air Force (USAF) via a Memorandum of Agreement with the USFS in 1950, the facility was transferred to NSF in 1976. NSF and the USFS executed a land use agreement (1980) to formalize this transfer and the continued use of the land for the NSO. It was later known as the Sacramento Peak Observatory , and as one site of the National Solar Observatory (NSO). In 2018, all scientific research and public outreach at

1980-542: The USAF itself. Much of the conversion work was done before the aircraft were removed from storage at AMARC, with further work being carried out at East St Louis , Illinois . The QF-106s began operating as a Full-Scale Aerial Target (FSAT) in late 1991 at White Sands Missile Range New Mexico, and later at the Eglin Gulf Test Range in Florida (based at Holloman and Tyndall). A typical mission would employ

2040-611: The base was planned to "be manned by a skeleton crew merely as a plane refuelling station, [for] emergency landings, etc.", and it was temporarily inactivated on 28 February 1946. Post-war the AAF was used to support the Alamogordo Guided Missile Test Base which had its first Boeing Ground-to-Air Pilotless Aircraft launch on 14 November 1947. With the September 1947 formation of the USAF, in late 1947

2100-548: The first dual-based tactical fighter wing. The 6583d Air Base Group was inactivated in place. Under the dual-basing concept, the 49th, stationed at Holloman, deployed individual squadrons periodically to Europe , fulfilling their NATO commitment. The operational squadrons of the 49th TFW upon its arrival were: All three squadrons flew the McDonnell Douglas F-4D Phantom II . In 1972 squadron aircraft tail codes were standardized on "HO". In 1969,

2160-501: The local sheriff. A local TV station provided a call-in from a supposed employee with a disguised voice, although this was later found to be faked by the reporter. On September 17 AURA re-opened Sunspot, following an investigation into criminal activity involving Apache Point Observatory personnel. Later, court documents reported that the closure was due to threats from the Apache Point Observatory janitor who

2220-410: The longest flight of a single-seat fighter aircraft. The flights required six aerial refuelings, proving the global power of the 49th Tactical Fighter Wing. In July 1980, the wing acquired the commitment of a primary Rapid Deployment Force unit. This tasking, which lasted for a year, required the wing to be ready to deploy its aircraft, crews, and support personnel on short notice. The wing served with

2280-539: The most valuable, and highly guarded targets in Serbia . The F-117s penetrated the heavily defended areas, which conventional aircraft could not reach, and at least two aircraft were lost. Global War on Terror People, airplanes, and equipment of the 49th Fighter Wing played a key role in the continued global war against terrorism and particularly in Operation Iraqi Freedom . The wing's F-117s played

2340-433: The need to organize its own long-range program of solar studies, it quite naturally turned for specialized assistance to the recently formed High Altitude Observatory (HAO)". In September 1947, the USAF issued a contract to HAO and Harvard University to conduct a survey and thereby identify an appropriate site for a new solar observatory and to determine which instruments to install at the new site. Any seasonal cloud cover at

2400-660: The new site needed to arrive in the opposite season to that at Climax, in order to then provide for year-round coverage of the Sun. Similar to Climax, the atmosphere above the new site should be exceptionally free from haze and dust in order to permit for the best possible observing. Roberts and Menzel examined the White Sands Proving Ground (an area used as a research rocket firing range near Holloman Air Force Base in Alamogordo, New Mexico). They "concluded that

2520-503: The range, a detached installation operated by the base was the Alamogordo Gasoline Storage and Pumping Station Annex . In 1944 the "base operating unit" changed to the 231st Army Air Force Base Unit (25 March) and 4145 AAFBU (24 August), and on 16 April 1945 Alamogordo AAF was relieved of its training mission and assigned to Continental Air Forces to become a permanent B-29 base. Instead, by 30 January 1946,

2580-649: The recommendation that Sacramento Peak be chosen as the solar research site for USAF. By April 1948, the Committee on Geophysical Sciences (then within the War Department's Research and Development Board) formally accepted this recommendation and a contract was written, mandating the Air Force to complete the observatory. The specifics of the contract called for "the preparation of detailed plans for an integrated solar research facility, which would combine observational, analytical, and data-reduction activities, all on

2640-412: The relative locations of the planets from the sun in proportion to their distance to Sunspot. On September 6, 2018, AURA voluntarily evacuated the site of Sunspot for security reasons. This prompted the formation of multiple conspiracy theories, including presence of aliens, military intelligence operations, impending solar storms, and FBI raids. These all originated from false information provided by

2700-461: The sandy background of the desert. On a clear day it is possible to see all the way south to the cities of El Paso, Texas , and Ciudad Juárez , Mexico, and all the way north to the Trinity test site . The overlook can also be used for viewing rocket launches from White Sands Missile Range . Sunspot, New Mexico Sunspot is an unincorporated community in the Sacramento Mountains in

2760-409: The section of the Sacramento Mountains in which Sacramento Peak is located would be especially promising for a solar research site. Further inquiries and inspection tended to confirm this initial reaction". Holloman Air Force Base could be used to supply the equipment and any supplies. Sacramento Peak was, at 9200 feet was also low enough to be more accessible to researchers than Climax at 11,000 feet and

2820-537: The telescope facility was taken over by the Sunspot Solar Observatory and AURA remain the operator of infrastructure on the site, including maintenance. Sunspot Solar Observatory is a global consortium that currently consists of personnel both in Sunspot, New Mexico , at New Mexico State University in Las Cruces, New Mexico , and other institutes across the world The flagship telescope at

2880-468: The thickly forested setting blocked interference from rising air currents up the mountain. A small crew of five made the initial camp at the Sunspot site. This crew included Roberts, John "Jack" W. Evans (a student of Menzel's), and Rudy Cook (who had worked with Robert in Climax). Cook's companions soon returned home, leaving Cook and his dog Rocky to man the site. By the end of 1947, Menzel and Roberts made

2940-496: The threat was no longer present, Sunspot was reopened by AURA. On September 24, 2018 Wired magazine published an article on the observatory. It stated that "Assuming New Mexico State gets a contract that goes till 2021, the site’s ultimate future may still be in flux. The National Science Foundation presented four potential ending options, and their impacts, earlier this year." Of these 4, NSF determined to keep Sunspot in operation in partnership with New Mexico State University. It

3000-415: The wing participated in its first dual-basing exercise, Crested Cap I, deploying 2,000 personnel and 72 aircraft to NATO bases in Europe. Also in 1969, the 49th earned the coveted MacKay Trophy for the "most meritorious flight of the year", for the redeployment from Germany to Holloman after Crested Cap II. The MacKay Trophy recognized the 49th for the fastest non-stop deployment of jet aircraft accomplished by

3060-455: The world's highest permanent observatory for astronomy, at an elevation of over 11,000 feet, and was designed purely for studying the Sun. Roberts worked with the Bureau of Standards, "forecasting radio conditions on the basis of solar observations". Such studies of the upper atmosphere were critical for predicting conditions for radio communication, guided missiles, and supersonic aircraft and, as

The Holloman Air Development Center became the base operating unit on 10 October 1952, and the 3,500 ft (1,100 m) rocket-powered sled was first run on 19 March 1954. On 10 December 1954, Lt Colonel (Dr.) John P. Stapp rode a Holloman rocket propelled test sled, Sonic Wind No. 1, to a speed of 632 miles per hour (1,017 km/h). The center

3240-515: Was awarded to Flight Systems Inc. (later Honeywell) to modify 194 surplus Convair F-106 Delta Dart aircraft stored at Davis-Monthan AFB Arizona to the QF-106A target drone configuration. This program came to be known as Pacer Six, and the first flight of a converted drone took place in July 1987. Following the completion of an initial batch of ten QF-106s in 1990, most of the work was transferred to

3300-441: Was delivered by Col. Kevin Zeeck on 18 November. The second, 72-1218, arrived at the base two days later. The remaining 14 F-4s arrived at AMARG by the second week of January 2005 in 4 further waves. The 48th Rescue Squadron was activated at Holloman AFB on 1 May 1993 with its six Sikorsky HH-60G Pave Hawk helicopters. The personnel of the 48th deployed six times in support of Operations Northern and Southern Watch. Additionally,

3360-554: Was designated Alamogordo Field Training Station (27 May) and Alamogordo Army Air Base (operated by the 359th Base Headquarters beginning on 10 June 1942). Alamogordo Army Air Field (Alamogordo AAFld, Alamogordo AAF) was named on 21 November as a Second Air Force installation equipped with aprons, runways, taxiways and hangars. From 1942 to 1945 the AAF had more than 20 different groups for overseas training, initially flying Boeing B-17 Flying Fortresses then Consolidated B-24 Liberators . Training began in 1943 and in addition to
