A. David Andrews (born 1933) is an Irish astronomer. He studied at Oriel College Oxford and University of Dublin. He spent the early 1960s in Denmark working with the astrophysicist M. Rudkjobing at the Aarhus Observatory. He moved on in 1963 to Armagh Observatory in Northern Ireland where he spent the next 35 years. Dr Andrews discovered the minor planet 1727 Mette (named after Andrews' Danish wife) whilst at the Boyden Observatory located in Bloemfontein, South Africa, where he was acting director. It was while at Boyden Observatory that he commenced his lifelong work on flare stars. He was the first to make full use of computers, in 1968, at Armagh Observatory. Andrews was Editor of the Irish Astronomical Journal following Ernst Öpik, and in 1967 became a founder member of Commission 27 Working Group on Flare Stars of the International Astronomical Union. The Boyden Station was created by Harvard University in 1889 in Arequipa, Peru, using Uriah A. Boyden's bequest to Harvard. In 1927 the renamed Boyden Observatory moved across continents to its present location in South Africa. This became the site of the Armagh-Dunsink-Harvard 36-inch Baker-Schmidt telescope utilized by Dr.E.M.Lindsay (Harvard & Armagh) and other Irish and international astronomers. In 1976 the Observatory was handed over to the University of the Orange Free State and the famous ADH telescope was dismantled. Some of its optical parts, including a 32-inch prism, were transferred to Dunsink Observatory, Dublin. Andrews then turned his attention to the new international astronomical facilities in Chile, and to available satellite technologies. Whilst 1727 Mette is by no means unique, it has been found that it belongs to the Hungaria family of asteroids which cross the orbit of Mars, and that it has a small companion orbiting it once every 21 days. This update comes from the Palmer Divide Observatory in Colorado Springs U.S.A. Asteroid 1727 Mette is 10 kilometers in diameter and rotates on its axis with a period of 2.98 hours. Its companion is about 2 kilometers in diameter. It has been suggested recently that 1727 Mette could make a close encounter with Mars in 2023, perhaps even a collision. This impact scenario sounds very much like that on Earth 65 million years ago when our dinosaurs were destroyed. In the Irish Astronomical Journal Andrews reported a suspected outburst of a B7 spectral type star in Auriga, BD +31 1048. This enigmatic object was
