2 Observing conditions

In 1995, observations were obtained on the nights of 24 August to 6 September. Full Moon was on 9 September. The observers were A Fitzsimmons and I M Cartwright for the nights of 24-30 August and D. Harper and K. Beurle for the nights of 31 August to 6 September.

In 1997, observations were obtained on the nights of 21-23 October. Full Moon was on 16 October. The observers were D. Harper and K. Beurle.

In both years, we used a TEK chip with 24 $\mu{\rm m}$ pixels, giving an approximate scale of $0\hbox{$.\!\!^{\prime\prime}$}33$ in the focal plane. The chip has a useful imaging area of $1024\times1024$ pixels giving a field of view of approximately $335\hbox{$^{\prime\prime}$}\times335\hbox{$^{\prime\prime}$}$.

A summary of the number of images of each target satellite is given in Table 1 and Table  2 which are extensions of Tables 2a and 2b respectively in Harper et al. (1997).
