V1028 CYGNI
David York, USA and Jochen Pietz, Germany have independently
reported a rare outburst of V1028 Cygni which is catalogued in the
GCVS as an SS Cyg type dwarf nova although there is some doubt
regarding this classification:
1995 July 28.186UT, 13.5 (D.York, USA)
          28.967UT, 12.7 (J.Pietz, Germany)
          29.217UT, 12.7 (D.York)
          30.216UT, 13.1 (J.McKenna, USA)
Taichi Kato, Japan e-mails the following comments:
We have obtained five hours' continuous good quality CCD V-band
light curve of V1028 Cyg July 29/30. The light curve shows a very
low amplitude (0.04 mag and 0.03 mag, alternately) double wave.  A
preliminary period analysis gives the best estimate of the period
as 0.0740 +/- 0.0010 day (assuming the double wave; the value is
still preliminary).  Such amplitude and profile rather commonly
exist in the earliest stage of superoutbursts of WZ Sge-type dwarf
novae.
Thus the present finding strongly support that V1028 Cyg belongs to
SU UMa-type dwarf nova which was observed during its earliest stage
of a superoutburst.  We expect in a few days the growth of tidal
instability will give rise to "usual" superhumps.  Since these
"early superhumps" are not been well understood, intensive and
continuous observations are highly recommended, especially in order
to compare the period with the orbital one and the ones expected to
appear later.

KEN GLYN JONES
We have learnt with regret from Don Miles of the death of Ken Glyn
Jones on 1995 July 26. He was the founder and first President of
the Webb Society which has become so well known throughout the
world for the development of deep sky observing.
