- 2005 September 08: S. F. Hönig reports in a paper accepted for publication in
Astronomy & Astrophysics
about the successful linkage of two SOHO comets. C/1999 R1 and C/2003 R5
seem to be identical. The orbital period is almost exactly 4 years. Both comets were
assumed to be members of a further possible comet group together with comet C/2002 R5 (SOHO).
In the paper it is shown that the latter comet might have been separated from the main
component at the end of the 19th century and thus strengthens the presented link.
The return of C/2002 R5 is predicted for summer 2006 (assuming a comparable orbital period
as the main component), while the return of C/1999 R1 = C/2003 R5 will occur on Sep. 11, 2007.
The chances for detecting the main component are higher because it is brighter than the fragment.
The paper is available as a pre-print.
- 04 September 2005: Tony Hoffmans possible Marsden group comet turned out to be
a 'sporadic' comet. Also the relation to C/2003 Q1 could not be confirmed.
