ZTFJ185139.81+171430.3 = ZTF18abnbzvx: not UG, but what is the type?

   I have obtained a period of 0.00858995(3) d from the data
for 2458645-2458747 (segment with relatively dense coverage,
including the night with time-resolved photometry).

   I'm not aware of a variable star with this amplitude
and short period with coherent modulations.  The profile
is almost sinusoidal, but the large amplitude makes it
unlikely type R (the period is also too short).

   At least not UG (no outbursts).
The period is in agreement with

185139.8 +171430 (2000.0) ZTFJ185139.81+171430.3 r=18.272 (17.561-18.836) P=0.0086
