It looks like Nick James’s observation on the evening of Oct 31 with an unfiltered magnitude of 14.81 marks the start of the outburst. With a JD of 2459519.29 this is only 56 days since the previous superoutburst but within the range of many recent results reported in VSSC 187.
Lets see how long this superoutburst lasts.
My next target is V1504 Cyg whose next superoutburst is due in a two weeks time.
