Exoplanet Light Curve

From http://brucegary.net/book_EOA/WebEOA/ExoplanetObservingAmateurs.html

This graph shows the light from a star measured over time. The amount of light goes down when the planet goes in front of the star and obscures some of the light.

About how many hours did the full transit take?

How much did the brightness of the star change from the beginning of the transit to the middle?
