Recently I often return home before reaching the observatory because of bad weather. The recent continuing rainy weather may suggest the onset of the rainy season. What's worse, Typhoon No.4 is moving north toward Japan and may bring us stormy weather.
I would like to express my sympathy to people near the epicenter of the recent severe earthquake in Northern Japan. I experienced the Great Nankai Earthquake(*1) in December 1946 and know fully well how frightening big earthquakes are. The eastern part of Kochi City was inundated and I went to my junior high school by boat. I recall the event rather sentimentally. I also remember that I was fishing near the river mouth in Urado Bay where the land rose and the water receded. Believe it or not, only three hours later the earthquake hit us.
Around 4 am when the earthquake occurred, a bright "comet" was glowing fuzzily in a cloudy dawn sky. I think it was Venus (not a comet), the same shining object I saw near the daytime sun during wartime in May, 1945. I wonder on which side of the sun Venus was at 4am on December 26, 1946.

Mr. Koichiro Tomita , a former Tokyo Astronomical Observatory staff member, inquired about a telescope owned by the Yamanouchi Family (a great feudal lord) in Tosa (Kochi). I sent him a number of photographs of the telescope. Photo 1 below is one of them I sent to Mr. Tomita and shows Mr. keiichiro Okamura, a researcher on astronomical history of Tosa, and myself.
The telescope seems to have been acquired about 200 years ago during the days of Yodo Yamanouchi, the last daimyo (feudal lord) of Tosa. There are also many armillary spheres among astronomical instruments preserved by the family. This telescope was made in Germany (by Schneider Optics) . Its aperture is 80mm with an f/15 focal ratio equipped with three eyepieces and a solar filter for astronomical use. It also includes a correct-image terrestrial eyepiece. In 1987 Dr. Marsden saw this telescope. I wonder who acquired this telescope for what purpose. Did the acquirer observe astronomical objects with this telescope? Is that person Yodo himself? Or is it Ryoma Sakamoto, who was always ahead of times with his foresight? Did Ryoma's thinking, which was much more global against the backdrop of the isolationist Japan, rise from the knowledge of the vastness of the universe, the insight he had acquired by observing the great universe? Or is this conclusion too hasty? Ryoma Sakamoto was born on November 15, 1835 and given the name Ryoma (galloping horse) , when Halley's Comet was blazing overhead. The comet was compared to a soaring dragon and galloping horse. In March 1986 I saw Halley's Comet through this telescope that Ryoma may have used. That beauty of the comet was unforgettable.

The heavens and the earth are both damp. It feels as if the rainy season is right at your doorstep. I came to the observatory for an evening comet search. Soon after twilight I found a firefly near the top of the dome flashing its light. A type of fireflies whose habitat is in the mountains are sometimes seen in the grass, but those flying in the air are rather unusual around Geisei. You will see them only once in five years or so. This firefly with a large green light flew high and mingled itself with the stars of Lyre, which had just emerged in the northeastern sky. It looked as if competing with Vega for superior beauty. I now understood what Mr. Hoei Nojiri had described in his poem. It was such a beautiful sight that you could not distinguish fireflies from stars.

I arrived at the observatory late at night. I looked for the firefly glowing in the grass which I had seen the previous night, but could not see any sign of it. Only starlight is seen in the heavens.
I remembered Mr. Hoei Nojiri's poem:
Constellations of fireflies glowing in the grass beautiful greenish blue.
Photo 1 is a portrait of Mr. Hoei Nojiri. This photo was taken when he appeared on NHK TV about 30 years ago. On the program he said he had crated the "Orion Memorial Cemetery. The Orion Memorial Cemetery...It sounds beautiful, doesn't it? Mr. Nojiri, I am sure, is sleeping in peace in this Memorial Cemetery.

Summer is just around the corner. The Milky Way was especially beautiful projected clearly against the southern sky. In the morning twilight I searched the eastern sky. M32 was barely visible near M31, though it was not seen yesterday morning due to its low altitude location. There was a big excitement on the morning of May 1, about 35 years ago, when five people discovered the same comet (Comet Tago-Honda-Yamamoto) around the same time.
The photograph shows M31. C/1968H1(Tago-Honda-Yamamoto) was discovered near M31 at 6th magnitude.
