6438 Suárez           Discovered 1988 Jan. 18 by H. Debehogne at the European Southern Observatory.
Buenaventura Suárez (1678-1750), a Jesuit and pioneer native astronomer of the Rio de la Plata, established the first observatory of the region in San Cosme y Damian, where he made observations in particular of eclipses of Jupiter's satellites. His Lunario de un Siglo included computations of eclipses and lunar phases.
