29P/Schwassmann-Wachmann 1, 64P/Swift-Gehrels, and 54P/de Vico-Swift-NEAT
29P is the famous comet Schwassmann-Wachmann 1. It is in
Gemini in the morning sky and brightening. A small round image at the center
of the photograph below is the comet with the coma 10" in diameter.
The photographic magnitude is 12. The GSC magnitude of the bright star
right above it is 10.1 and the visual estimate of the comet's magnitude
will be about 11.
64P is the comet Swift-Gehrels, which was discovered a century
ago. Though faint, it is still visible. This comet is also seen low in
the eastern sky in the morning.
54P is the comet de Vico-Swift-NEAT. Comet de Vico, which
had been discovered in 1844, was rediscovered by Swift in 1894 and named
de Vico-Swift. Since then there had been no observation of this comet until
it was found in 1965. Then, it disappeared again and no observation had
been made since. However, Mr. Kenji Muraoka suggested that P/2002 T4 discovered
by NEAT in 2002 is identical with de Vico-Swift. As a result, it was renamed
de Vico-Swift. I found old observations made in 2002 with the 60cm reflector
and made measurements again, which subsequently have been checked for residuals
by Mr. Hirohisa Sato. The image in the photographs was very faint and poor,
far from perfect.
