The solar analogues are fundamental targets for a better understanding of our Sun and Solar System .
Notwithstanding the efforts , this research is usually limited to field stars .
The open cluster M67 offers a unique opportunity to search for solar analogues because its chemical composition and age are very similar to those of our star .
In this work , we analyze FLAMES @ VLT spectra of about one hundred of M67 main sequence stars with the aim to identify solar analogues .
We first determine cluster members which are likely not binaries , by combining both proper motions and radial velocity measurements .
Then , we concentrate our analysis on the determination of stellar effective temperature , using the analyzes of line-depth ratios and H \alpha wings .
Finally , we also compute lithium abundance for all the stars .
Thanks to the our analysis , we find ten solar analogues , which allow us to derive a solar color ( B - V ) = 0.649 \pm 0.016 and a cluster distance modulus of 9.63 \pm 0.08 , very close to values found by previous authors .
Among them , five are the best solar twins with temperature determinations within 60 K from the solar values .
Our results lead us to do further spectroscopic investigations because the solar analogues candidates are suitable for planet search .
