No remarkable brightening in ASAS-SN Sky Patrol (Shappee et al. 2014ApJ...788...48S and Kochanek et al. 2017PASP..129j4502K) observations, which are contaminated by nearby stars:

*** Follow-up observations (e.g. spectroscopy, multiband photometry) are urgently required. ***
Clear skies,

Hi Patrick,
I need to finish performing a proper data reduction, but based on visual comparison with Johnson V-band images I acquired earlier today remotely from Siding Springs, yes it seems to be @ ~16 Vmag.
I'll do my best to get more data in the coming days.
