  A full-sky H-alpha map with 6 arcmin (FWHM) resolution is presented. This map
is a composite of the Virginia Tech Spectral line Survey (VTSS) in the north
and the Southern H-Alpha Sky Survey Atlas (SHASSA) in the south. The Wisconsin
H-Alpha Mapper (WHAM) survey provides a stable zero-point over 3/4 of the sky
on a 1 degree scale. This composite map can be used to provide limits on
thermal bremsstrahlung (free-free emission) from ionized gas known to
contaminate microwave-background data. The map is available on the WWW for
public use.
