COMET 1998 U2
     J. Mueller reports her discovery of another comet on plates
taken by herself (with K. Rykoski on Oct. 22) with the 1.2-m Oschin
Schmidt Telescope in the course of the Palomar Outer Solar System
Ecliptic Survey.  The comet has strong condensation and a short,
faint tail to the southeast.  The following positions were reduced
by G. V. Williams, Smithsonian Astrophysical Observatory, from x,y
measures provided by Mueller:

     1998 UT             R.A. (2000) Decl.        m1

SUPERNOVAE 1998ej AND 1998ek IN ANONYMOUS GALAXIES
     J. Maza, Department of Astronomy, University of Chile, reports
the discovery of two supernovae by Roberto Antezana on T-Max 400
films taken by L. E. Gonzalez with the Maksutov telescope at Cerro
El Roble:

SN      1998 UT         R.A.  (2000)  Decl.    Mag.     Offset
1998ej  Oct. 15.201  23 41 00.95  -38 56 37.2  19    4".1 W, 6".5 N
1998ek  Oct. 15.341   6 36 30.59  -37 58 40.2  18   14".0 E, 4".3 N

SN 1998ej was confirmed via B and V direct images taken by D.
Gonzalez on Oct. 17 with the YALO telescope at Cerro Tololo, but it
is not visible on a film obtained at Cerro El Roble on Sept. 28.223
(B > 19.5).  SN 1998ek was confirmed on a T-Max 400 film taken by
L. E. Gonzalez on Sept. 28.378 with the Cerro El Roble telescope,
but it is not visible on a film obtained with the same instrument
on Aug. 28.379 (B > 19.5).


COMET C/1998 T1 (LINEAR)
     Total visual magnitude estimates:  Oct. 13.77 UT, 14.6 (M.
Lehky, Hradec Kralove, Czech Republic, 0.42-m reflector); 13.85,
14.3 (K. Hornoch, Lelekovice, Czech Republic, 0.35-m reflector);
17.03, 14.5 (Lehky); 20.90, 13.7 (Lehky); 21.83, 13.9 (Hornoch).
