This 300 m image from 4 August 2014 shows the smoke plume of the largest Swedish wildfire in 40 years in the province of Västmanland (about 150 km northwest of Stockholm). The fire started at 31 July and lasted until 11 August, burning down an area of about 1,500 km² and forcing more than 1,000 people from their homes (source: Wikipedia and Wallstreet Journal Online).
