My two primary targets are the well-known eclipsing dwarf novae OY Car and Z Cha. I intend to take high-speed spectra of these. However if conditions are poor (as seems likely from the weather forecast) I may have to go to my backup program which is to look at dwarf novae in outburst. In this case I am interested in detecting the very short period oscillations called dwarf nova oscillations that these stars sometimes show. Therefore I am interested in reports of any southern hemisphere dwarf novae in outburst; the brighter the better. From what I can gather, HL CMa is a good target at the moment, but please let me know of any others too, thank you and good observing, Tom Marsh
