8898 Linnaea           Discovered 1995 Sept. 29 by G. Emerson at Golden.
Linnaea Barton Keammerer (1980-1992) died in an accidental shooting. An avid student of nature, she was told while observing comet 1P/Halley in 1986 that she would almost certainly live to see it again. Linnaea enjoyed writing poetry: "One star silent in the sky, Twinkling, yet I don't know why."
