We also have:

2016 Oct 24.42 UT; m1= 13.8; Dia= 0.4’; DC= 5/6; 25cm L, f:5 (x166) [Chris Wyatt, Walcha, NSW, Australia]

So that places the time of outburst at 2016 10 24.63 +/-0.17

Nice work Jean-François and Chris. We appear to have witnessed another good example of one outburst triggering a second one: in this case after just
