ACOS Bulletin

History

The Australian Co-ordination Section (ACOS) of the Centre for UFO Studies operated from PO Box 546, Gosford, New South Wales, publishing its Bulletin from 1975 through 1979. H. Greisberg and David Seargent served as co-editors. The publication functioned as the Australian arm of J. Allen Hynek's CUFOS network, applying the same scientific methodology Hynek advocated in the United States to Australian case data.

The Bulletin ran to 22 issues over five years, with contributors drawn from across Australian states. Keith Basterfield (South Australia) contributed extensively on close encounter classification and entity reports. Bill Chalker wrote on CE3 experiences in Australia. David Seargent handled analytical pieces including a notable debunking of the sunspot-UFO correlation theory that had been presented at UFOCON TWO by Stan Seers of Queensland.

The Bulletin's content was analytical rather than anecdotal. The June 1977 issue alone contained a statistical analysis of sunspot correlation claims, a time-pattern study of close encounters (distinguishing "accidental" from "deliberate" encounters), a status report on Australian entity cases (73 events catalogued by Basterfield's Entity Study Group), and a piece asking whether Zeta Reticuli could host an alien civilisation.

Subscriptions supported production, and the editors reminded readers through multiple issues that the Bulletin relied entirely on subscriber income. The publication was registered as a Category C publication under Australian postal regulations.
