Reports from Geisei Observatory <August 18, 2009>
The following is the observation of Swift-Gehrels visible
low in the dawn sky. This is the first observation of this comet at Geisei
in 18 years after the last observation (recovery) in 1991. It is strange
that this comet discovered by the American comet hunter Swift a century
ago is still being observed. I also think the claim not necessarily correct
that short period comets disappear in 100 years. It is true that this comet
have faded by several magnitudes since Swift discovered it visually because
it loses its brightness as it revolves the sun.
The comet is diffused with a week central condensation. The
total magnitude was given here.
It is already autumn in the sky and at 4 o'clock in the morning
Orion rising before dawn.
