Hi Kearn & All,
Yes I noticed a similar effect surrounding the Sun today in Sydney after about 1.30pm -- an extended, bright weakly yellowish halo of scattered light around the Sun and about 25 degrees diameter. I too concluded it was probably forward-scattered light from the stratospheric volcanic aerosol and ash cloud from the Puyehue-Cordon Caulle volcano in Chile.
It is not uncommon to see such an effect on exceptionally windy days (from dust) but the size of the halo (much bigger) and the colour was different to normal and while it was very breezy during the morning, the wind was not exceptionally strong.
Best,
Les D
