IX Dra was at V mag 17.9 on 20 Sept 04.42 UTC marking the end of the superoutburst. Almost immediately a normal outburst has started. I think the start of this superoutburst was recorded well and I expect a few more observations to appear in due course.
Thanks to N D James and N L Joslin for observations in the BAA database.
The next superoutburst will be around fireworks night!
