2.5-m telescope in their 1999 Intermediate Redshift Supernova

SN1999cj was discovered about 7 days past maximum.  SN1999ck was
discovered about 5 days before maximum.  Both objects were
confirmed with spectra obtained on Apr. 19 at the William Herschel

     Another apparently asteroidal object discovered by LINEAR
(discovery observation below; additional astrometry on MPEC 1999-
K44), and posted on The NEO Confirmation Page, has been reported as
cometary on May 27 by L. Sarounova (Ondrejov; coma diameter at
least 30" with condensed nucleus), by M. Tichy and Z. Moravec
(Klet; 10" coma), and by R. A. Koff (Thornton, CO; diffuse coma of
diameter about 8").
