   We propose a second ASCA observation of the (usually) X--ray bright
   polar, EF Eri, to be simultaneous with already accepted XTE and EUVE
   observations. The initial ASCA observation is insufficient for this
   purpose as the system has been in an extended low state for the past
   two years, so its accretion geometry may be very different when the X-
   ray emission resumes. Simultaneous data are essential in order to build
   a reliable composite broad band spectrum, with unprecedented spectral
   coverage from 0.4--60 keV, enabling the continuum shape, reflection
   spectrum, complex continuum absorption and emission line properties to
   be studied in detail.
