CH CYGNI
There has evidently been a sharp increase in the brightness of
CH Cygni, a star on the BAAVSS programme, as shown in the following
results:
1998 July 1.933UT, 9.1v (Guy Hurst, Basingstoke 15x80B); 13.065,
8.8v (Gary Poyner, Birmingham); 17.724, 8.1p (H.Maehara, Japan,
200mm telephoto with T-Max 400); 18.938UT, 8.3v (Hurst)

SUPERNOVA 1998cv IN ESO 237-G42
J. Maza, Department of Astronomy, University of Chile, reports
the discovery of a supernova (B about 17.5) by Roberto Antezana on
a T-Max 400 film taken by L. E. Gonzalez using the Maksutov
telescope at Cerro El Roble on June 24.315 UT.  The supernova is
located at R.A. = 22h09m46s.29, Decl. = -49o47'43".0 (2000), which
is 5".0 east and 12".7 north of the nucleus of the spiral galaxy
ESO 237-G42 (IRAS 22064-5003).  SN 1998cv is not present on a film
obtained with the same telescope on May 30.355 (B > 20).

SUPERNOVA 1998cw IN ANONYMOUS GALAXY
Maza also reports that another supernova (B about 17.5) was found
by Antezana on a film taken as above on June 24.365 UT.  SN 1998cw
is located at R.A. = 22h56m19s.67, Decl. = -35o09'59".9 (2000),
which is on top of a small, faint galaxy (which is smaller than 3"
on the Digitized Sky Survey).  SN 1998cw is not present on a film
obtained with the same telescope on May 30.374 (B > 20), but it was
confirmed by Phillips with the the Blanco 4-m telescope on June 27.

SUPERNOVA 1998cx IN NGC 6209
A. Wassilieff, Palmerston North, New Zealand, reports his
discovery of an apparent supernova (mag about 17.8) on July 4.412
UT with a 0.36-m f/4.3 reflector (+ unfiltered SBIG ST-7 CCD).
G.Nankivell, Wainuiomata, Lower Hutt, N.Z., provides the following
measurement for the position of SN 1998cx from a July 4 image by
Wassilieff:  R.A. = 16h54m55s.31, Decl. = -72o35'24".0 (2000),
which is 10".9 west and 12".1 south of the nucleus of NGC 6209.
Further rough magnitudes from Wassilieff:  July 5, 17.8; 16, 18.3.
SN 1998cx does not show on a CCD image taken on 1993 Aug.
18, nor is it evident on a second-generation Digital Sky Survey
image.
