On July 5 (Fri.), the ninth lecture of the KCG Group's 50th anniversary, " Nationwide Simultaneous Tanabata Lecture @ KCG - Astronomical Topics in 2013 are the Arrival of a Great Comet" by Prof. Kazushi Sakka of Kyoto Graduate Institute of Information (KCGI), was held a-ERR:REF-NOT-FOUND-t the Kyoto Station Satellite Main Hall of Kyoto Graduate Institute of Information (KCGI), which also served as the first part of the KCG Summer Festa 2013 event astronomy workshop.Prof. Sakka explained about the large meteorite that fell in Russia in February this year and Comet ISON, which comes in early winter, and talked about the fascination of faraway space to the general public and students who visited.In the evening, there was the second part of the astronomy workshop by the students of KCG Astronomy Club.

Professor Sakka began by referring to the fall of a large meteorite in Russia. "The meteorite was about 17 meters in size," he said, "but the city was enveloped in a bright white flash, and the shock wave that followed caused panic in the area.In fact, in 1908, a meteorite about 50 meters in diameter fell in Siberia, an uninhabited area east of the present meteorite, at the same latitude of 60 degrees north," he explained.If the time had been off and it had fallen on a major European city at 60 degrees north latitude, we might not have had World War I because we would have had to deal with it," he said.He explained that the meteorite that fell on Mexico's Yucatan Peninsula 65 million years ago, which caused a cold snap that killed the dinosaurs, was 10 to 15 kilometers in diameter, had a magnitude of 11 or higher, and generated a tsunami of 300 meters in height. In Japan, there were meteorites such as the Nogata meteorite (861, Fukuoka Prefecture, the oldest confirmed case) and the Taue meteorite (1885, Shiga Prefecture, Japan's largest, weighing 175 kilograms).

He said, "The year 2012 was called the Golden Year of Astronomy, and the annular solar eclipse was the main topic of conversation.This year's topic will be the arrival of comets," he said. "From the end of November to the beginning of December, Comet ISON will arrive with a long tail, which will be as bright as the full moon at 11th magnitude.Let us hope that in Japan, too, we will be able to view its majestic form in the eastern sky before sunrise.Comets observed in the world and in Japan were also introduced.

In the second part of the workshop by the KCG Astronomy Club, after an explanation of the legend of Tanabata, the students observed the stars that can be seen in Kyoto during this season using the astronomical simulation software "Stellarium" and thought about the stars shining on the computer.

The "All-Japan Tanabata Lectures" is an event sponsored by the Astronomical Society of Japan, in which lectures on astronomy and the universe are held simultaneously in various parts of Japan during the period before and after Tanabata Day (July 7) and the traditional Tanabata Day (August 13).More than 100 events will take place this year.

In the workshop, members of KCG Astronomy Club explained about the Tanabata legend.
