A Carrington Rotation is a single rotation of the Sun. This was first measured in the 1850's by Richard Carrington, using sunspot groups as markers. A Single Carrington rotation is taken to be 27.3 days. It is worth noting that the Sun is a fluid and rotates at different velocities depending on the Suns latitude, about 25 days at the equator and at around 30 days at the pole. Therefore, the 27 days is somewhat arbitrary!

Each Solar rotation, starting from November 9 1853, is given a number. The above image is taken from Carrington rotation 2125 and is a link to a movie made with images taken from the PROBA2 satelite, it shows Carrington Rotations 2125 & 2126.
