We present the first speckle interferometric observations of Mira's hot companion. The companion accretes mass from Mira's wind and provides an excellent opportunity for studying the accretion processes in detached binaries. The separation between the components of the system is crucial for accurate determination of the accretion rate onto the companion. Speckle measurements of the separation made at three epochs since 1983 with much higher precision than previous visual observations show that the companion's distance from Mira is substantially larger than expected.
