We hope nobody would say that a big "UFO" appeared when the Puyehue volcano erupted (taking into account the foolishness of some people).
Lenticular cloud at one side of the column of smoke and ashes coming out from the volcano. Impressive photography!
Lightning bolts strike around the Puyehue-Cordon Caulle volcanic chain near southern Osorno city June 5, 2011. The volcano in the Puyehue-Cordon Caulle chain, dormant for decades, erupted in south-central Chile on Saturday, belching ash over 6 miles (10 km) into the sky, as winds fanned it toward neighboring Argentina, and prompted the government to evacuate several thousand residents, authorities said.
