Meteorite WIS91600: A New Sample Related to a D- or T-type Asteroid

Since the Tagish Lake meteorite fell in January 2000, the assumed one-of-the-kind meteorite has become the hottest issue among a diversity of scientists. Meanwhile, as the physical origin of the meteorite in our solar system, D or T asteroids have been suggested by Hiroi et al. based on comparison of their visible-near-infrared (VNIR) reflectance spectra. While it is probably still true that the Tagish Lake meteorite is possibly the first recovered sample from a D or T asteroid as a meteorite fall, we report in this paper that the meteorite WIS91600 may actually be the first recovered sample from one of those asteroids as a meteorite find.
