The young planet β:Pictoris b offers the rare opportunity to monitor a large fraction of its orbit using the imaging technique over a reasonable timescale. Using NACO at VLT, we obtained repeated follow-up imaging observations of the β:Pic system in the K_s and L' filters over 2010 and 2011. Together with past measurements, we have conducted an homogeneous analysis of data, that covers more than 8 yrs. We then derived the most probable orbital solutions that fit our measurements using a least-square algorithm and a Markov-Chain Monte Carlo approach. The solutions favor a low-eccentricity orbit e⪉0.2, with semi-major axis between 8--11.5 AU corresponding to orbital periods of 15--25 yrs. Our solutions also favor highly inclined solution with a peak around i=88.5° revealing a probable tilt with a perfectly edge-on configuration. We also derive prediction for transiting events. The solution is consistent with the planet being responsible for the 1981 transiting event. Finally, the planet seems compatible with former predictions linked with the cometary activity in the β:Pic system.
