Red sky at night

The night skies over Britain will turn a deep shade of crimson this week as the fallout from a Russian volcano blast hits the UK. Millions of tonnes of dust, ash and sulphur dioxide were thrown up to 30 miles into the air when Sarychev Peak on Matua Island in the Kuril Archipelago erupted last month. The blast created what experts call a ‘volcanic aerosol’ - a colourful mixture of ash and sulphur compounds - in the stratosphere. This scatters an invisible blue which, when mixed with the red light of the setting sun, produces a ‘volcanic lavender’, or vivid crimson/violet hue. Strong winds blew the soaring plume more than 2,000 miles across the northern hemisphere before its effects were noticed in Britain last Thursday. The RARE phenomenon has been caught on camera. Meteorologists say the sunset spectacle will last for several days, but will only be visible on clear evenings. It will then continue on its journey across the Atlantic and into the skies above North America
