9541 Magri           Discovered 1983 Feb. 11 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Christopher Magri (b. 1961) is a scientist at the University of Maine at Farmington. A former galactic radio astronomer, he has used analyses of radar echoes from main-belt minor planets to demonstrate that there is no radar evidence for a difference between the surface bulk densities of the S and C objects.
