The start of the still ongoing (rather slow) brightening was announced in
http://ooruri.kusastro.kyoto-u.ac.jp/mailarchive/vsnet-alert/25688
 
It has been confirmed by Yasuo Sano (see Taichi Kato's message below)
and now also by ASAS-SN:
https://asas-sn.osu.edu/sky-patrol/coordinate/45f536fe-7971-49a9-b980-b5a492ee8fd2
 
Time-resolved photometry is required.
 
Clear skies,
Patrick
