COMPUTER DIFFICULTIES AT TAHQ
During recent weeks severe computer difficulties have prevented
the usual comprehensive service being provided on these circulars
although thanks to the temporary access to a second computer the
most urgent announcements have still be made. Unfortunately action
on incoming e-mails has suffered such that at this time the editor
is running about 840 e-mails behind in reading and sending replies
where needed. Again messages marked urgent have been dealt with
on the second computer. If anyone has an urgent message not yet
answered please re-send with 'urgent' mentioned in the subject
line.

SUPERNOVA 1999ga IN NGC 2442
S. Woodings, R. Martin, and A. Williams, Perth Observatory, report
their discovery of an apparent supernova (R about 18) on
Nov. 19.76 UT in the course of the Perth Astronomy Research Group's
automated supernova search with the Perth-Lowell 0.61-m reflector.
J. Biggs and A. Verveer provide the following position for SN
1999ga from two unfiltered CCD images obtained on Nov. 22.54 with
the 0.25-m Mike Candy Telescope at Perth Observatory:
R.A. = 7h36m16s.70 +/- 0s.03, Decl. = -69o33'21".8  (2000.0), which
is about 38" west and 91" south of the centre of NGC 2442; the
magnitude of the new star was estimated as 18.5 +/- 1.   IAUC 7316

SUPERNOVA 1999gb IN NGC 2532
A. Friedman 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 supernova in NGC 2532.  SN 1999gb was discovered and
confirmed on unfiltered images taken on Nov. 22.4 (mag about 16.1)
and 23.4 UT (mag about 15.9). SN 1999gb is located at:
R.A. = 8h10m13s.70, Decl. = +33o57'29".8 (2000), which is 18".6
west and 6".2 north of the nucleus of NGC 2532. IAUC 7316 (extract)

SUPERNOVA 1999gc IN ANONYMOUS GALAXY
J. Maza, University of Chile; and M. Hamuy, University of Arizona,
report the discovery by R. Antezana, on a 20-min unfiltered T-Max
400 film taken by L. Gonzalez on Nov. 10.25 UT with the University
of Chile's Maksutov telescope, of a supernova (mpv about 17.5)
located at:
R.A. = 1h05m10s.87, Decl. = -20o17'48".1 (2000), which is 6".7 west
and 10".7 north of the nucleus of the host galaxy.  The supernova
was confirmed by L.-G. Strolger (University of Michigan) from
B,V,R,I images taken with the Cerro Tololo 1.5-m telescope on
Nov. 16.                                        IAUC 7317 (extract)

SUPERNOVA 1999gd IN NGC 2623
W. D. Li, University of California at Berkeley, on behalf of the
Lick Observatory Supernova Search, with the 0.8-m Katzman
Automatic Imaging Telescope (KAIT), reports the discovery of an
apparent supernova in NGC 2623.  The supernova was discovered and
confirmed on unfiltered images taken on Nov. 24.5 (mag about 17.8)
and 25.6 UT (mag about 17.4), respectively.  The new object is
located at: R.A. = 8h38m24s.61, Decl.= +25d45'33".1 (2000), which
is 7".3 east and 17".4 north of the nucleus of NGC 2623.
