The aim of this project was to investigate the radial velocity variations of the Sun as observed from the Earth. This was accomplished by observing Doppler shifts of spectral lines in the region around 6300 Å. Telluric O2 lines were used as reference. The results indicate that during the day, the radial velocity increases and reaches a peak some time in the afternoon. Over spring, the radial velocity slowly declines. These results were compared to predicted values from JPL, NASA, and when accounting for the errors, they mostly agree with the predictions.
