1994 03 15.04 &1 All observations by Heraudeau et al. (since March 11) are
1994 03 15.04 &2 done with the 1.2-m OHP telescope, equipped with a 512 x 512
1994 03 15.04 &3 Tektronix CCD camera, plus a filter system described by
1994 03 15.04 &4 C.Chevalier and S.A.Ilovaisky in Astron.Astrophys.Suppl.Ser.
1994 03 15.04 &5 90, 225 (1991). The photometry is calibrated from aperture
1994 03 15.04 &6 photometry on the galaxy and the measurements are colour
1994 03 15.04 &7 corrected.

1994 03 20.692 &1 Results are preliminary. Magnitudes are calculated WITHOUT
1994 03 20.692 &2 color correction. Because of large difference of colors
1994 03 20.692 &3 between the SN and the comparison (KKM 9), there exists
1994 03 20.692 &4 fairly large systematic deviation from the standard system.
1994 03 20.692 &5 Non-photometric condition has not allowed determination of
1994 03 20.692 &6 the color terms. Galaxy background has been more explicitly
1994 03 20.692 &7 removed assuming point symmetry of the galaxy. These
1994 03 20.692 &8 comments also apply to subsequent measurements by T. Kato.
