  We present results of a microvariability polarization study in the violently
variable quasar 3C279. We have resolved the polarization curves in the V band
for this object down to timescales of minutes. We found two main components in
the evolution of the degree of linear polarization, one consisting of a flicker
with timescales of several tens of minutes and other component with far more
significant variations on timescales of a few days. The linear polarization
descended from $\sim 17$ % down to $\sim 8$ % in three nights. The polarization
angle underwent a sudden change of more that 10 degrees in a few hours, perhaps
indicating the injection of a new shock in the jet. The amplitude of the
intranight flickering in the degree of polarization is at the level of $\sim
1$%. These are probably the best sampled polarization data ever obtained for
this object. We also performed IR observations and we provide a follow-up of
the evolution of this source at such energies after the main polarization
outburst.
