EDITORIAL ABSENCE
The editor will be away and not contactable from the morning of
March 7 and will return late on March 10. During that period please
refer any URGENT messages to Nick James or Denis Buczynski but
send additional copies to the editor's mailbox for review upon
my return.

SUPERNOVA 2001W IN MCG +07-34-134
T. Puckett, M. Marcus, and D. George, Mountain Town, GA, report the
discovery of an apparent supernova (mag 17.5) on an unfiltered CCD
frame (limiting mag 20.5) taken with the Puckett Observatory 0.60-m
automated supernova patrol telescope on Feb.26.46 UT.  SN 2001W is
located at R.A. = 16h41m15s.09, Decl. = +39o17'44".5 (2000), which
is 0".1 west and 20".6 north of the centre of MCG +07-34-134.  The
new object was also present and confirmed on CCD frames taken on
Feb. 28.34 with a 0.40-m reflector by J. Newton at Chiefland, FL.
SN 2001W does not appear on unfiltered images taken by Puckett on
2000 June 29, July 8, and Aug. 23 or on Palomar Sky Survey images
taken on 1993 Apr. 30, 1989 May 31 (limiting mag about 21.0), and
1953 May 19 (limiting mag about 19.7).

SUPERNOVA 2001X IN NGC 5921
W. Li, University of California at Berkeley, communicates that
Y. Fan, Y. L. Qiu, and J. Y. Hu, on behalf of Beijing Astronomical
Observatory (BAO) Supernova Survey, report the discovery of an
apparent supernova (mag about 17.0) found on an unfiltered image
taken with the BAO 0.6-m telescope on Feb. 27.8 UT.  SN 2001X is
located at R.A. = 15h21m55s.45, Decl. = +5 03'42".1 (2000), which
is 15".5 west and 32".4 south of the nucleus of NGC 5921.  SN 2001X
was confirmed on an unfiltered image taken by M.Schwartz on
Mar. 2.5 with the Tenagra Observatory 0.5-m automatic telescope,
from which Li measured the position end figures to be 55s.46
+/- 0s.03, 43".1 +/- 0".2, and the magnitude of the supernova to be
15.2.  Images of the same field taken with the BAO 0.6-m telescope
on Feb. 6.9 (limiting mag about 17.5) and with the Tenagra 0.5-m
telescope on Feb. 17.5 (limiting mag about 18.0) showed nothing at
this position.  Li remarks that a normal type-Ia supernova in this
galaxy might reach mag about 13.

V4643 SAGITTARII
N.N.Samus, Institute of Astronomy, Moscow advises that the above
designation has been assigned to the object formerly known as
Nova Sagittarii 2001 and announced on E1611.

Akimasa Nakamura writes on VSNET that Akihiko Tago (Tsuyama,
Okayama, Japan) has informed him that his photographic observations
of V4643 Sgr provide the following magnitudes:

2001 Feb. 19.863 UT fainter than 10.0
     Feb. 22.860 UT fainter than  9.8
     Feb. 26.870 UT mag. 9.5 (sequence : GSC)
Instruments: 105mm F/4 lens + unfiltered T-max 400 film
He adds that since the Feb. 22 observation was made only 36 hours
earlier than Liller's  discovery, it seems to be important to know
how fast the nova rose.
