November from 18th to 19th, 2001.
I counted up 1126 meteors, though an irresponsible way of counting. It was an highest scale of meteor stream I have ever seen. As about a few hundreds of shooting stars at most through a night in the normal year, I counted them without breaks in the beginning.
It was cloudy the night before the day and the early evening of the day, but it was clear through the night.
I think stars of the third or fourth magnitude can be seen at Kitamoto, Saitama. I tried 15 minutes fixed exposures, but they were out of focus in the beginning, and after that, the lens got wet with the evening dew, then, few photographs were successful. I got six shooting stars in a roll of 24 exposure film.

Meteor trails, fireballs (no records of the time and numbers). Shooting stars had length from 0 degrees to 45 degrees or might have more. Generally those nearer to Leo are shorter, farther are longer. Duration are from a flash to long enough to make a wish. Some meteor trails remained a few minutes, gradually snaking and becoming dim. I think most shooting stars are in the Leonids, because they radiated from Leo. As a parking space of Saitama-Kenmin-no-Mori, Saitama prefectural forest park, where I often go to see stars, is cut off the eastern view, I did not have recognized they radiate. Meteors tend to shoot continuously. When I caught sight of something shooting in an edge of my eyes, I often watch others in the direction. They sometimes falled four or five ways at a time. I could witness meteors at everywhere I see around when the Leonids were most active. I guess they shot one per a few seconds.
NHK news reported that the stream peak was about 3:20 a.m. and meteors were observed at the rate of 5000 an hour in the place on good condition.
