TELECOM GOLD
I am delighted to announce that I have restored contact with members
of our group on Telecom Gold. This is via a GOLD mailbox linked to
my PRESTEL box. The Telecom Gold number is: 10074:MIK2885. I can
also be contacted on PRESTEL via 256471074.

CY UMA
Patrick Schmeer reports a superoutburst of this recurrent object:
1990 Sept 11.124UT, [12.6; 14.156,12.0; 15.160,12.4:; 16.799,12.7:
He suggests that high speed photometry is needed to search for
superhumps. Previous recorded supermaximum: 1988 Oct 29.

V482 CYGNI
Gary Poyner, Birmingham, reports a further fade of this R-CrB type
variable: 1990 Sept 2.87UT, 11.4; 9.92, 11.5; 17.91UT, 12.4.
According to TA 1990 September, one observer reported it at 12.5
on Aug 26 but there is inconsistency in the August results.
A delayed report from P.Schmeer has reached us also confirming
a fade in September: 11.968UT, 12.5; 17.019, 13.0.
