AB: We present early measurements by the STEREO/WAVES and IMPACT instruments of bow shocks, interplanetary shocks, and in situ interplanetary type III bursts. S/WAVES measures spectral density and 'burst' electric waveforms on three orthogonal antennas. IMPACT burst mode samples the thermal and suprathermal electrons and magnetic field at high cadence for several 10 minute intervals each day. The S/WAVES and IMPACT bursts systems have triggered together on several occasions at shocks and foreshock electron beams. Here we present results of these high time resolution bursts. Early in the mission, several in situ IP type III bursts were observed at 1 AU by STEREO and Wind. The similar instrumentation on the three spacecraft (with separations greater than 100 Re) allows us to limit the spatial extent of the type III radio emission region.
