ASAS-SN has observed a rapid, two magnitude brightening of the flat spectrum radio source PKS~2345-16 (z=0.576, 23:48:02.6, -16:31:12), from g<17 to g~15.3 mag over 15 days from UT 2018-06-23 to UT 2018-07-09.12. The ASAS-SN g-band (green and yellow) and V-band (blue) light curve is available here.

We encourage multimessenger analysis of this interesting source.
