Long quiescence before superoutbursts

Forums Variable Stars IX Dra: observations requested Long quiescence before superoutbursts

Stewart John Bean

Looking at the last superoutburst graph ( up this forum on Jan 12th ), I see that there was quite a gap between the last normal and  the normal outburst that led to the superoutburst. Immediately after a superoutburst the normals come every 3 – 4 days. Later they seem to be separated by 5-6 days. In the graph on the 12th Jan, it seems that there was a 7 day separation between the last two normals.

On this basis the next normal might be on the 12th. This one might trigger the superoutburst. If so it will be 5 days late relative to the recent long term average.
