    The active K-type star, Speedy Mic (HD 197890), is one of the most   
    rapidly rotating (0.3 days rotation period) cool dwarf stars yet dis-
    covered, & is also a strong & variable source in the extreme ultra-  
    violet that was detected in the ROSAT All Sky Survey with the Wide   
    Field Camera. We propose to make an ASCA observation of this young   
    disk star that will extend over 2 rotation periods so as to determine
     its X-ray spectral characteristics and to obtain a record of its    
    coronal spectrum as a function of rotational phase.  We will search  
    for possible spectral variability due to the rotational modulation of
     compact emission regions and/or of cool, absorbing clouds that have 
    been inferred to be present and might occult underlying coronal      
   structures.
