1994 04 05.6 &3 This and the following observations by Sadakane et al. were
1994 04 05.6 &4 made from the campus at Osaka Kyoiku University. They used
1994 04 05.6 &5 a 51-cm f/12 reflector and a LN 12 cooled CCD camera, which
1994 04 05.6 &6 was mounted at the Cassegrain focus. The typical exposure
1994 04 05.6 &7 times were a few minutes in all bands. Data reductions and
1994 04 05.6 &8 measurements were carried out by using the APPHOT package
1994 04 05.6 &9 in IRAF. (From a message to Dr. Yamaoka, via T. Kato.)

1994 04 08.8 &2 Mags. for this and other observations by Sadakane et al.
1994 04 08.8 &3 have been revised as the previous measurements were severely
1994 04 08.8 &4 affected by the variable sky level around the SN. They now
1994 04 08.8 &5 use a smaller aperture with radius equal to the FWHM of the
1994 04 08.8 &6 stellar image and the sky value is estimated just outside
1994 04 08.8 &7 the aperture.
