7124 Glinos           Discovered 1990 July 24 by H. E. Holt at Palomar.
Canadian amateur astronomer Tom Glinos (b. 1960) has contributed observations in several fields for almost a quarter of a century. He recently donated a high-quality equatorial telescope mount to the London Centre of the Royal Astronomical Society of Canada, a group with which he has been long active.
