With the launch of the Solar Dynamics Observatory (SDO) we now have access to images of the Sun, combining unprecedented spatial and temporal resolution. Understanding meridional flow patterns on the Sun is one of the keys to unlocking the secrets of the solar dynamo, and thus unraveling the nature of the solar cycle. In this work we attempt to measure solar meridional flows by analyzing data from the Helioseismic and Magnetic Imager (HMI) aboard SDO. We discuss possible techniques to be used, and present some preliminary results.
