   The galaxy cluster around the compact radio galaxy 3C129.1 is the
   ninth-brightest cluster in the sky in the 2-10 keV band. Because of
   its low Galactic latitude it has been little studied at optical or
   X-ray wavelengths. In fact it is the only cluster of the brightest
   thirty that has yet to be observed with ASCA. Previous X-ray imaging
   observations of the 3C129.1 cluster did not allow the amount of
   cooling in the intra-cluster medium to be determined with
   satisfactory precision. Thanks to the cluster's X-ray brightness the
   ASCA observation proposed here will provide spectra of exceptional
   quality which will enable us to search spectrally for cooling
   components. The proposed observation will also allow us to measure
   the X-ray flux from the well-known twin-tailed radio source 3C129.
