16887 Blouke           Discovered 1998 Jan. 28 by the OCA-DLR Asteroid Survey at Caussols.
Morley Blouke (b. 1941) is a well-known microelectronician, whose pioneering development of thinned CCDs gave rise to the WF/PC I focal plane. He now heads advanced development at Scientific Imaging Technologies, Inc., in Tigard, Oregon.
