The recent discovery of a bowshock around the HMXRB Vela X-1 in the optical and infrared, indicating that the system is moving supersonically with respect to the interstellar medium, prompted a search for a radio counterpart. Observations were made of Vela X-1 using the Australia Telescope Compact Array at 3, 6, 13 and 20 cm. Although the resulting maps show no emission above the noise level from the bowshock, the upper limits on the bowshock's radio emission allow constraints to be put on the density of the shocked gas.
