Abstract

The 1.0m telescope at Sutherland (SAAO, South-Afrika) was used to image the objects (17493) WILDCAT, (22653) 1998 QW2, 2006 FZ51, 2006 GZ42, 2006 HH89. All of these asteroids have orbits with a Tisserand parameter close to 3, corresponding to the boundary between asteroidal and cometary orbits (Hsieh and Jewitt 2006 Science, 312, 561). Short exposure sequences of 30 to 60 seconds per frame were acquired between 2006-06-01 and 2006-06-11, giving a total exposure time of 45 to 60 minutes per object.
