The ESO Public Survey VISTA Variables in the Via Lactea (VVV, https://vvvsurvey.org) mapped the IR variability of the Milky Way bulge and southern mid-plane. The VVV eXtended Survey (VVVX) covers the gaps left between the VVV and VHS areas and extend the VVV time-baseline enabling proper motion measurements of -1 in the optically obscured regions where Gaia is limited by extinction. VVVX covers 1700 sq degrees in the Southern sky, from l <=130deg to l = +20deg.
