  We repeat the directional spherical real Morlet wavelet analysis, used to
detect non-Gaussianity in the Wilkinson Microwave Anisotropy Probe (WMAP)
1-year and 3-year data (McEwen et al. 2005, 2006a), on the WMAP 5-year data.
The non-Gaussian signal detected previously is present in the 5-year data at a
slightly increased statistical significance of approximately 99%. Localised
regions that contribute most strongly to the non-Gaussian signal are found to
be very similar to those detected in the previous releases of the WMAP data.
When the localised regions detected in the 5-year data are excluded from the
analysis the non-Gaussian signal is eliminated.
