Time system is Universal Time. Magnitudes were calculated from Pogson's
step method. CL = class: estimated accuracy of observation; 1 = good
(+/- 0.1 mag.), 2 = fair (+/- 0.2 mag.). Instrument (aperture in mm):
M = reflector, C = Schmidt-Cassegrain. New or revised observations since
Report No. 5 (1993 June 5) are marked with an asterisk (*).
