We have secured a week of observing time (6-12 january 1998 inclusive) on the 1.9m and 1m telescopes at SAAO, South africa to study the hot disc of the nova-like V347 Pup which shows evidence for tidal structure. We would be very interested in any dwarf novae in outburst during these nights, visible in the southern sky. The large accretion discs found in the early outburst phase of dwarf novae are particularly susceptible for the tidal forces of the companion star. As it is crucial to catch the discs as early in outburst as possible we would like to receive visual magnitude estimates of such dwarf novae. We would appreciate a direct e-mail to us (see addresses below) as soon as new observations are available to prevent any delays. Many thanks and good observing!
