An update on IX Dra recent behaviour. Observations are been made by the AAVSOnet telescope in New Mexico, by BAA-VSS, and by AAVSO members.

The most recent superoutburst was well recorded by AAVSOnet telescopes with a start around JD 2459688.

TESS contributed a detailed record of the superoutburst at JD 2459633.

The previous superoutburst was well recorded at JD 2459577.

The next previous superoutburst was well recorded on JD 2459520.

Graphing the most recent data gives the data in the attachment. This shows a declining trend from a peak around 60 days. The data point at JD 2459106 is almost certainly too high owing to limited observations. Observations were available only once the outburst had started so the start must be uncertain by a few days.

It seems that for IX Dra the trend towards longer superoutburst periods has paused. It may be reversing.

Thanks to all who have, and continue to, contribute to following this star.
