Windows of low extinction in the Milky Way (MW) have been used along the pastdecades for the study of the Galactic structure and the stellar populationacross the inner bulge and disk. Here we report the analysis of another lowextinction near-IR window discovered by the VISTA Variables in the V\'iaL\'actea Survey. VVV WIN 1733$-$3349 is about half a degree in size and isconveniently located right in the MW plane, at Galactic coordinates $(l, b) =(-5.2, -0.3)$. The mean extinction of VVV WIN 1733$-$3349 is $A_{Ks} =0.61\pm0.08$ mag, which is much smaller than the extinction in the surroundingarea. The excess in the star counts is consistent with the reduced extinction,and complemented by studying the distribution of red clump (RC) stars. Thanksto the strategic low-latitude location of VVV WIN 1733$-$3349, we are able tointerpret their RC density fluctuations with the expected overdensities due tothe presence of the spiral arms beyond the bulge. In addition, we find a clearexcess in the number of microlensing events within the window, whichcorroborates our interpretation that VVV WIN 1733$-$3349 is revealing the farside of the MW bulge.

VVV WIN 1733$-$3349: a low extinction window to probe the far side of the Milky Way bulge
