SUPERNOVAE 1999en, 1999eo, 1999ep, 1999eq, 1999er
L.-G. Strolger, University of Michigan and Cerro Tololo
Interamerican Observatory (CTIO); R. C. Smith, CTIO; E. P.
Rubenstein, CTIO; A. Soderberg, Bates College and CTIO; and T.
Bowers, University of Arizona, report the discovery by the Nearby
Galaxies Supernova Search team of the following supernovae in their
Sept. 27-Oct. 4 search using the Kitt Peak 0.9-m telescope:
SN      1999 UT      R.A.  (2000.0)  Decl.     R       Offset
1999en  Oct.   3   1 15 29.70   - 4 30 48.2   19:    0".5 E, 4".2 N

V452 CAS
Further to the note on E1469, Gary Poyner, Birmingham, England
reports his observations of the recent outburst:
Nov 9.781UT, 14.9; 10.014, 15.3; 16.972, 15.4; 19.960, [15.0.
He adds that the observations by Chris Jones and himself are the
first ever visual observations of an outburst of this star.
Chris Jones, Laindon, England confirms his positive observations
were definitely of the northern component (cf E1469).
Nick James, Chelmsford, adds that his image of 1999 Oct 10 does
NOT show an outburst when compared with the positive brightening
on Martin Mobberley's picture of Nov 9.

COMET C/1999 U4 (CATALINA-SKIFF)
T. B. Spahr, Lunar and Planetary Laboratory, have reported the
discovery by the Catalina Sky Survey on 1999 Oct 31 of a
slow-moving object that was independently discovered by B. A. Skiff
(measurer B.W. Koehn) by the LONEOS survey. In response to Skiff's
alert, R.L. Millis and L. H. Wasserman, on a 5-min R-band exposure
with the Perkins 1.8-m reflector, detected a coma extending 8"
southeastward from the nucleus:
Orbital elements by Dan Green:
     T = 2001 Sept.14.404 TT          Peri. =  77.087
                                      Node  =  31.540   2000.0

COMET 141P/MACHHOLZ 2
On Oct. 17 R. H. McNaught, Research School of Astronomy and
Astrophysics, Siding Spring Observatory, reported his single-night
detection of another component of this comet, with m2 fainter by
0.5 mag but with brighter m1 and a larger coma (diameter 8", as
opposed to 5") that night than the object reported on IAUC 7231
(presumed to be the 1994 component A, which he measured to be 260"
to the east and 346" to the north).  It seemed likely that the new
object was component D.  On Oct. 23 S. Nakano reported an
independent detection of the new component by A. Sugie, Dynic
Observatory, on Oct. 21 (m1 = 16.2, coma 10") and 23 (m1 = 17.3),
and calculations by him and by Brian Marsden confirmed this to be
component D. On Oct. 31 H. Luthen, Hamburg, reported the
photographic detection by M. Jager, Vienna, on Oct. 27 and by Jager
and G. Rhemann on Oct. 29 and 31 of an object with a 1'.5-2'.0 coma
and m1 = 12.8-13.0.
