Query: Photometric observations of Rosetta target asteroid 2867 Steins   Asteroid 2867 Steins is one of two flyby targets of ESAs international
Rosetta mission, launched in March, 2004. We obtained photometric observations
of Steins on April 14-16, 2004 at Table Mountain Observatory, California, in
order to characterize the asteroid physically, information that is crucial for
planning the Steins flyby. This study includes the first detailed analysis of
the physical properties of Steins from time-series R-filter data along with V-
and I-filter photometric measurements.
