  Title: IS THE STARTBURST GALAXY M82 A HOST OF AGN ?                                    


Abstract:
 We exame if AGN exists in the famous starburst galaxie M82. Observations with ROSAT
 and ASCA of M82 show followings; 1) A soft nuclear point source with
 Lx=(3-6)e+39ergs/s was detected with ROSAT and showed time variability during the
 ROSAT observation. 2) A hard point-like source was detected with ASCA and Ginga at
 the nuclear region. The Xray luminosity has changed from 4e+40ergs/s to 2e+40 ergs/s
 between the two observations. 3) The ROSAT source and ASCA/Ginga hard source are
 different as they have different positions. The observational results show suspicion
 that M82 maight be a host of AGN. Ascertain the truth, we obtain deataled both soft
 and hard band images placing the M82 nuclear at the 1CCD mode nominal position, and investigatin a long term time variabilty.

REMARKS:  AS THE DETECTION OF LONG TERM VARIABILITY IS ESSENTIAL IN THIS
          OBSERVATION, INTERVAL AMOND MONITORINGS IS VERY INPORTANT. PLEASE CONSULT
          PI BEFORE FIXING THE LONG TERM OBSERVATION SCHEDULE.
