At 4 o'clock in the morning, October 10, 1956, a 10th-magnitude
comet entered the field of my 15cm comet seeker. It was Crommelin's Comet,
which had appeared 28 years earlier. It was Pajdusakova of Skalnate Pleso
Observatory in Czechoslovakia (presently in Slovakia), who had rediscovered
the comet, but it is not widely known that Mr. Minoru Honda and I had independently
rediscovered it, too.
This comet was discovered by Mr. Masamitsu Yamasaki at Mizusawa
Latitude Observatory in October, 1928. About one month later, Mr. Forbes
of South Africa discovered it, though his "discovery" was more
like confirmation of Mr. Yamasaki's discovery. However, Mr. Yamasaki's
name is not found in Marsden's famous Comet Catalog, in spite of the fact
that he was awarded the Donohoe Comet Medal from Astronomical Society of
Pacific for the discovery. It was much later that this comet was determined
to be a periodic comet and was given the name of Crommelin.
In 1984 I saw this comet in the evening sky. It was at 7th
to 8th magnitude and disk-like without a tail. It will return around 2012.
10-minute exposure from 20:30, February 29, 1984 J.S.T.
60cm f/3.5 refelctor
