   We propose to carry simultaneous observations of the bright contact
   binary 44 Boo with ASCA and with the EUVE satellite. The simultaneous
   observations, thanks to the complementary contraints supplied by the
   different passbands of the two instruments, will allow us to study
   the differential emission distribution and the metal abundance in the
   corona of a contact binary system, over the complete temperature
   range from hundred thousand to several tens of million degrees. This
   will allow us to address for the first time through simultaneous
   observations the apparent incompatibility between the ASCA and EUVE
   derived DEM of several active binaries. Additionally, the period of
   the target is short enough and the count rate high enough as to allow
   phase-resolved spectroscopy.
