The cloud of smoke caused by raging bushfires in Australia has been spotted more than 12,000 kilometres (7,400 miles) away in Chile and Argentina, weather authorities in the South American countries said on Monday.
In the early hours "the effect was seen in the sun through red tones. This effect was produced by a cloud of smoke that comes from the fires," Chile Meteorology chief, Patricio Urra, told AFP.
The cloud has risen to 6,000 metres (6,500 yards) above sea level and there is no meteorological reason for it to fall back to earth, said Urra. It poses no threat to Chileans.
The Argentine Meteorological Service published satellite images of the cloud saying it had been "transported by frontal systems that move from west to east."
