  The gamma-ray binary system LS I +61 303 was studied in great detail in VHE
gamma-rays in the last years by the MAGIC telescope. The VHE emission of the
system exhibited a prominent periodic outburst in the orbital phases 0.6-0.7
between September 2005 to January 2008. In Fall 2008 the Fermi collaboration
reported as well periodic emission in the MeV to GeV energy range, but with a
shifted outburst in the phases 0.35-0.45. MAGIC observed again LS I+61 303 in
2009 with the twice more sensitive stereo mode to allow for detailed
correlation studies between the VHE gamma-ray and Fermi/LAT energy band. Here
we present our new results, which show a significant reduction in the VHE
gamma-ray flux in the phase of the periodic outburst by almost one order of
magnitude compared to our previous measurements. Furthermore, the 0.1-phase
averaged light curve shows no significant outburst, but a rather constant flux.
Here we will discuss the implications of our results for future gamma-ray
studies of LS I +61 303.
