Coolant leaking, it looks like its leaking from the sensor?

Where is the this picture taken from? It looks like under the engine in the front, if so I would say it is the water pump. Please go over this guide to help confirm the leak:

I would use a flashlight to help check the weephole of the water pump. Please upload pictures or videos in your response of any problems.
