Additional observations through March 13, 1996 have been supplied by the Minor Planet Center and used to update the orbit, ephemeris, and error analysis. Although very uncertain, the formal osculating orbital period is now 16,400 years.

This comet will not approach the Earth's orbit at either orbital node so that
an associated meteor shower is unlikely.
