    HR1099 is the brightest RS CVn system in the X-ray and EUV.  We      
    propose to observe HR1099 with ASCA for 40 ksec, contemporaneous with
    EUVE and IUE spectroscopy.  To ensure overlap with these satellites, 
    we are forced to ask for a time critical observation during the      
    period 24-27 August 1994.  The ASCA observations will cover a        
    significant fraction of the orbital period.  The ASCA count rate is  
    high enough that good phase resolution for rotational modulation or  
    time resolution of flaring is possible. ASCA spectra will show the   
    very hottest plasma in the coronae of these stars.  We will derive   
    the coronal+transition region emission measure distribution, electron
    densities and abundances, using ASCA, EUVE, and IUE spectra,         
   calculate models of the atmosp
