Based upon observations from both VSS and AAVSO members, the graph below indicates the onset of the January superoutburst.
I estimate the start time to be JD 2459224.2 which in turn gives a supercycle period of 61.7 days since the November event. Start times are arbitrary but in the absence of a definition (any ideas?) you have to go with something. The average value for P(sc) is then 60.5 days over the last eight cycles. Variations from this average only seem to be a few days so, with fingers crossed, we can mark our calendars for March 11 for the next superoutburst.
