Bright periodic comet, but it had not been discovered until 1990. At
the discovery, it had already passed the perihelion two months before,
and faded out rapidly. So, it was supposed to be a temporary
outburst. But it was observed at the same brightness in the next
return in 2007.
This comet tends to brighten and fade out rapidly. And the light curve
is asymmetric to the perihelion. It reaches to the maximum brightness
about 50 days after perihelion passage.
Kazuo Kinoshita's calculation revealed that the orbital elements of
this comet have not been changed so much since 1888. So it is expected
to show the same light curve in every apparition.
