We report the results of more than 30 h of VLA monitoring at 6 cm of the radio emitting X-ray binary LSI+61 303. Small amplitude (∼4mJy) radio flares have been detected superposed onto the early decay of the expected periodic radio outburst of this source. Such kind of microflares seem to exhibit a recurrence period of 1.4 h. Among different possibilities, we interpret them tentatively as caused by secondary luminosity driven shocks. In addition, we report and discuss the detection of linear polarization in LSI+61 303 at the ∼2% level during one of the observing sessions.
