The VVV eXtended Survey (VVVX) will cover the gaps left between the
VVV and VHS areas and extend the VVV time-baseline enabling proper motion
measurements of <0.3 mas yr-1 in the optically obscured regions where Gaia
is limited by extinction. VVVX will take 2000 hr, and cover 1700 sq degrees
in the Southern sky, from l ≤ 130deg to l = +20deg (7 h < RA < 19 h).
VVVX will provide a deep JHKs catalogue of about 2x109 point sources,
as well as a Ks-band catalogue of ∼107 variable sources.
