COMET C/1999 U1 (FERRIS)
     B. Koehn, Lowell Observatory, adds that the discovery images
(cf. IAUC 7283) show this object as clearly cometary, with a coma
diameter of about 9" and a fan-shaped tail extending 18" from the
comet toward the south.  Additional astrometry and the following
preliminary parabolic orbital elements appear on MPEC 1999-U19:

     T = 1998 Aug. 17.978 TT          Peri. = 268.285

NOVA IN IC 1613
     J. Y. King, M. Modjaz, and W. D. Li, University of California
at Berkeley, on behalf of the Lick Observatory Supernova Search,
report the discovery with the 0.8-m Katzman Automatic Imaging
Telescope (KAIT) of an apparent nova in IC 1613.  The nova was
discovered on unfiltered images taken on Oct. 12.3 UT (mag about
18.6), and confirmed on unfiltered images taken on Oct. 13.3 (mag
about 18.8).  Inspection of the KAIT archive data shows that the
nova has been in KAIT images since Aug. 23, all with magnitudes
about 18.5.  The new object is located at R.A. = 1h04m48s.97, Decl.
=  +2o05'28".8 (equinox 2000.0).  A KAIT image of the same field on
Aug. 18 (limiting mag about 19.0) showed nothing at the position of
the nova.  IC 1613 is a dwarf galaxy in the Local Group.


NOVAE IN THE SMALL MAGELLANIC CLOUD
     Clarifying the title on IAUC 7286, it is to be noted that the
novae reported on IAUC 7121 and 7239 should be called 'Nova in the
Small Magellanic Cloud 1999 No. 1' and 'Nova in the Small
Magellanic Cloud 1999 No. 2', respectively.
