9611 Anouck           Discovered 1992 Sept. 2 by E. W. Elst at the European Southern Observatory.
Anouck Vrouwe (b. 1978) studied physics at Nijmegen, specializing later in scientific journalism. At Davros (Switzerland), she has been involved with the study of wind velocities in order to derive models for the prediction of avalanches.
