    PR # 31544                                                                   
     We propose an ASCA observation of the Seyfert 1 galaxy NGC985. Our pr       
     evious ROSAT study of NGC985 strongly suggests that it may possess a        
     warm absorber, i.e. partially ionized material along the line of sigh       
     t to the primary X-ray source.  We will search for spectral features        
     associated with such a warm absorber, including time variation of the       
      absorption.  The purpose of such studies is to determine the physica       
     l state, location and structure of the warm absorbing material. Featu       
     res produced by warm material may prove to be an important diagnostic       
      for models of Seyfert galaxies and unified AGN models.
