The
dwarf nova EX Draconis shows deep and wide eclipses, in addition to its
frequent outburst activity (every 2-3 weeks), which makes it the ideal
target for monitoring a complete outburst cycle. We observed EX Draconis
in BVI colours with the 1.2m telescope at Kryonerion Korinthias (Greece)
between 1 July-20 August 2000 covering 3 outburst events (1-5 July,
20-30 July and 6-12 August). Here, we present a preliminary eclipse
mapping study of the light curves obtained in August 2000. |
