| The long soft edged purple shadows crossing the pink twilight are characteristic of those seen after volcanic eruptions. Sulfate aerosol from Sarychev was still circulating the Northern hemisphere at this time and could have produced the bright twilight with contrasting shadows. however, colourful twilights occur at any time - they do not necessarily need a volcano. |
