  dmag = SN - HHM 9 (V=12.56, B=13.61, Rc=12.04, Ic=11.61)
  mag: calculated WITHOUT color correction

  observer: T. Kato
  telescope: 60-cm reflector at Ouda Station (Kyoto University)

  * In calculating magnitudes, no color correction has been applied.
    Because of large difference of colors between the SN and the comparison,
    there exists fairly large systematic deviation from the standard system.
    (Non-photometric condition has not allowed determination of the color
    terms.)
  * Galaxy background has been more explicitly removed assuming point
    symmetry of the galaxy.
    Result of re-analysis on Mar. 20 data are also given.
