The effects were felt around the world and included a temporary global cooling and a thinning of the ozone layer as well as other changes in the global weather pattern. However, the most obvious effect for many people was a milkiness in the daytime sky due to scattering by high altitude aerosols, and corresponding anomalous sunsets and twilights that were noticable for years.
This picture was made in early 1992, a little after sunset from alongside the AAT dome at Siding Spring, looking west. Not only was the colour of the sky unusual, but the yellow-orange glow extended almost overhead. At this time the stratospheric dust was still in sunlight and reflected the colours of the setting sun widely across the sky. At this time the twilights themselves were greatly extended and a red horizon glow remained for visible several hours after sunset. Its reflection in the AAT dome is seen here.
