    A radio pulsar was found in the NW bright spot inside this composite
    SNR.But whether this radio pulsar is really associated with the SNR
    is not confirmed yet. We will observe at the radio pulsar position to
    see if we can find a X-ray pulsar. Even if we cannot find pulsation
    there,we can at least get spectral information of the bright spot and
    the nebula around it."Asca" can determine whether the spectra are non
    -thermal or not. We can see the relationship of the bright spot and
    the nebula.This SNR is center-filled and the source of energy or the
    confinement mechanism is not well known. We will also observe the
    geometrical center to see if we can find another compact star. We
    propose to observe each points for 30ksec.
