   Here is the result for 175345.53-334810.1 = OGLE-BLG-LPV-104139.

   This gives a fainter maximum than at Gaia19bih
(shown in vsnet-alert 23208)
indicating that the variation by ASAS-SN at 175345.53-334810.1
is contamination from Gaia19bih.

It's rather queer that the light curve for
ASASSN-V J175345.53-334810.1 is almost non-variable,
and the period is far from the OGLE variable.

It's likely that the position by ASAS-SN was heavily
weighted toward this brighter object, but what ASASSN
discovered (I suspect it may be contaminated Gaia19bih).
