Description
We are using the longest and densest unbiased observing campaign obtained at TeV and GeV energies during 5.5 years with the FACT telescope and the Fermi LAT detector together with contemporaneous multi-wavelength observations to characterize the variability of the source and constrain the underlying physical mechanisms. We study and correlate light curves obtained by ten different instruments and found two significant results. The TeV and X-ray light curves are very well correlated with a \textbf{lag $<0.6$ day}. The GeV light curve accurately leads the variations observed at long wavelengths and in particular in the radio band by 43 days with a broad response.
