9070 Ensab           Discovered 1993 July 23 by C. S. Shoemaker and D. H. Levy at Palomar.
Leo Enright (b. 1943) and Denise Sabatini (b. 1950) of Ontario are one of the foremost couples in Canadian amateur astronomy. Leo is an accomplished solar and auroral observer and has written the Beginner's Observing Guide. Denise's interests center on archeoastronomy and in providing access to astronomy for the disabled.
