On the 11th June 2009, Sarychev Peak volcano erupted on Matua Island one of the Kuril Islands, Russia in the Pacific Ocean. It pumped millions of tonnes and tonnes of sulfur dioxide and ash into the stratosphere. These aerosols can produce spectacular sunrises, sunsets and twilights and this was the case after the Sarychev eruption. some of the most spectacular and beautiful sunsets that I have seen. September was the peak of it.
