Can you see any volcanic ash up higher? To me, in the picture at least, it looks like a beautiful day!

Airports operator BAA confirmed that all flights at Heathrow, Stansted and Gatwick would be suspended from midday.
"Air traffic restrictions have very properly been applied," said Dr Rothery. "If volcanic ash particles are ingested into a jet engine, they accumulate and clog the engines with molten glass."
In 1982, British Airways and Singapore Airways jumbo jets lost all their engines when they flew into an ash cloud over Indonesia.
Reports said that the ash sandblasted the windscreen and clogged the engines, which only restarted when enough of the molten ash solidified and broke off.
A KLM flight had a similar experience in 1989 over Alaska.
Stewart John, a fellow of the Royal Academy of Engineering and former president of the Royal Aeronautical Society, explained that the ash can cause severe damage.
"This dust really is nasty stuff," he told BBC News. "It's extremely fine and if it gets into a jet engine, it blocks up all of the ventilation holes that bleed in cooling air.
"Jet engines operate at about 2,000C, and the metals can't take that. The engine will just shut down."
In the case of the 1982 British Airways flight, Mr John explained, when the plane emerged from the cloud, the pilot repeatedly tried and failed to restart the engines
