Abstract (from CDS):
Superoutbursts were reported on 1983 Nov. 30, 1986 May 3, 1988 Sept. 1, 1990 June 30, and 1993 Apr. 25. Regular outbursts were reported on 1984 Dec. 17, 1987 July 1, 1989 Aug. 12, 1994 Apr. 23, and now 2006 Oct. 7. Among the five superoutbursts, the average inter-outburst interval is approximately 859 days (± 192 days). After onset of four of the five superoutbursts, a regular outburst is seen approximately 379 days (± 46 days) later. Also, during the approximately-11.5-year interval covered by these five superoutbursts and follow-up regular outbursts, no other confirmed regular outbursts were observed. A search of ASAS2 and ASAS3 data by A. Henden, AAVSO, shows no reliable observations for 1997-2004; the 2005 ASAS3 data were not available. Two positive observations (D, or very poor, quality) in the ASAS2 data were contradicted by numerous fainter-than observations in the AAVSO International Database and so are discounted.
