A milestone for V1159 is approaching.
According to the observations in the AVVSO record for V1159 Ori, it is now 98 days since the last superoutburst. This exceeds the previous interval of about 70 days. So either the observations have missed a superoutburst or we continue to see normal outbursts but no superoutburst. I am inclined to think that conditions for triggering a superoutburst are not present. Longer intervals between superoutbursts has been the trend for V1159 Ori. At this rate, if V1159 Ori were discovered today it would not meet the criteria for being classed as a ER Uma type CV. However, normal outbursts do continue and these may be a better guide to classification – which is arbitrary anyway.
Once the next superoutburst occurs and provides another data point on the graph, I will write up for the VSSC.
