  Title: VARIABILITY AND SPECTRAL STUDY OF NGC4258 (M106)                                


Abstract:
 We propose 3 times 33 ks observations of NGC4258 (M106). M106 is a nearby (6.4 Mpc)
 spiral galaxy classified as a LINER. ASCA observed it in PV phase and found a
 strongly absorbed hard emission, presumably from a low luminosity AGN. The most
 wonderful thing about M106 is that its central (maybe) black hole mass and
 inclination angle are precisely determined by VLBI observations of water maser in
 1995. We are planning to study variability and spectral feature especially Fe-K line in detail.
