M. Oda and the Hakucho Team, University of Tokyo, telex: "As
of Sept. 26 there has been no sign of burst activity from the Rapid
Burster since Hakucho started continuous monitoring on July 14.
Because of the sun-angle constraint observations must now cease, and
Hakucho will not observe the source again before 1981 Mar."
