referred to by Prof.G.Haro as "Andrews' Star". This was a discovery made in his earliest work on flare stars and solar-related phenomena which he pioneered at Armagh Observatory. Andrews collaborated with several groups in U.K., U.S.A., especially with Dr.D.J.Mullan (Armagh & Bartol Research Inst.), and S.America, Russia, Armenia, Italy and Greece. He cooperated with Prof.G.Haro, director at the Tonantzintla Observatory in Mexico on stellar flares in young stellar clusters. Collaboration with Dr.W.E.Kunkel (Univ.Texas) and Sir Bernard Lovell at the Jodrell Bank radio telescope led to one of the earliest detections of large radio flares in UV Ceti-type stars, in the dMe star YZ CMi. What Andrews had fortuitously observed at Armagh in 1968 turns out to have been what is now termed a stellar megaflare (also see Apache Point Observatory). In 1981 Andrews published from the Armagh Observatory his multi-colour (UBVI) measurements of over 16000 stars in a region rich in flare stars on Schmidt photographic plates, "A Photometric Atlas of the Orion Nebula". He used material from the SRC/UK Schmidt in Australia and the European Southern Observatory (ESO) and the Las Campanas Observatory (Univ. Toronto) in Chile. In the Irish Astronomical Journal he published a "Cyclopaedia of Telescope Makers" in seven parts in the 1990s. From 1984 he was actively engaged in the search for quasi-periodic ultraviolet and infrared variations in flare stars indicative of active regions and stellar rotation. He also collaborated with the Armagh astronomers, Drs.C.J.Butler, P.B.Byrne, J.G.Doyle and P.Panagi, and Japanese, Italian, U.K. and U.S. astronomers, especially Prof.J.Linsky, in observations of the chromospheric rotation of RS CVn and BY Dra stars with the International Ultraviolet Explorer satellite. Andrews, now retired, and his asteroidal wife, Mette, live in Dore, a village on the outskirts of the beautiful S.Yorkshire and Derbyshire border, near Sheffield U.K., where he enjoys a life of painting, music, cycling and his family.
