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 very preliminary. No colour correction has been
1994 03 20.692 &2 applied. Subtraction of galaxy background has partly been
1994 03 20.692 &3 taken into account by using PSF photometry. The comparison
1994 03 20.692 &4 star was HHM 9. These comments also apply to other measure-
1994 03 20.692 &5 ments by T. Kato on this date.
