SUPERNOVAE 1999cj AND 1999ck IN ANONYMOUS GALAXIES
     In addition to the information supplied on IAUC 7182, D.
Hardin reports the following magnitudes and redshifts deduced from
the Apr. 19 spectra obtained at the William Herschel Telescope:  SN
1999cj, R = 22.0, z = 0.360; SN 1999ck, 21.9, 0.432.  The discovery
magnitude for SN 1999cj was R = 22.0, not 19.2 as indicated on IAUC
7182.
