The perihelion distance is large as 4.3 A.U., and the orbit is almost
circular with an eccentricity of 0.12. Kenji Muraoka's calculation
revealed that this orbit does not change significantly for 200 years
in the 20th and 21st centuries.
It reaches 17.5 mag at best based on the brightness at the discovery
in 2007 January. The brightness in 1996 February coincides with it.
However, the comet was unexpectedly bright as 15.5 mag only in 1975
May and June. It seems to be a temporary outburst. In this apparition,
the comet returned to be its normal brightness in 1977 July as 18 mag.
This comet is similar to 111P/Helin-Roman-Crockett; large perihelion
distance, almost circular orbit, and a record of unexpected
brightening in temporary outburst.
