Spot the difference

This is a photo taken from outside our office. It is the view we usually have on a day to day basis. Turned out a little dark, so I have tried to make it brighter.
This photo was taken about 10 minutes earlier. Can you spot the difference?

Most the time we are completely unaware of Mount Cameroon. Yesterday we were going back to the office after lunch and could see the whole thing. Its massive and looks so close. It was the first time we have seen the whole thing. It is amazing how we can never see it because of clouds.
