On 13 July 2020 the National Museum of Nature and Science reported in a press release<\/a> that on 1st July at 17.32.03-10 UT (2nd July JST) a meteorite fell into a condominium in Narashino, Chiba Prefecture, in Japan. At 2.32.03-10 a.m. JST a large fireball of about 7 seconds was widely seen and detonation sounds were heard above the Kanto region. The meteorite, an ordinary chondrite (H5), fragmented when it hit the railing of a shared corridor facing the courtyard in front of a door of an apartment at location 35\u00b041\u201926″N, 140\u00b001\u201951″E<\/strong><\/a> and fragmented on impact. <\/p>\n\n\n\n

I’m glad I noticed. I would like to see the meteorites at hand displayed at museums and other places. (Finder of the meteorite.)<\/p>\n\n\n\n

The first meteorite fragment weighing 63 grams (45 x 30 x 25 mm) was found by a woman living in an apartment. She was sleeping at home on the second floor of her apartment when she woke up and heard something impacting the railing in the corridor. She was too afraid to go out and have a look because she thought someone had thrown a stone at her home. The next morning she found a four-centimetre stone in the corridor and noticed the dent in the railing. Scratches from the impact could still be seen on the railing of the corridor. She did not know the stone was special and left it where it was. It wasn’t until she became aware of media reports about the fireball during the night that she went out to pick the meteorite up and contacted a nearby museum. On 4 July the woman and the caretaker looked for more fragments of the meteorite outside in the courtyard of the first floor and then found a second fragment (70 grams, 50 x 35 x 20 mm) which had been exposed to terrestrial weathering for two days and already showed obvious signs of corrosion. Additionally, another 15 smaller pieces (22 grams) were found on the terrace of the fifth floor. Senior researcher Naoki Takahashi visited the fall site on 5 July. He took the meteorite and brought it to National Science Museum for a first analysis. On 1 November 2020 the fall was added to the MetBull as Narashino<\/strong><\/a> (H5, S1). From 10 November to 13 December 2020 Narashino meteorite fragments were exhibited together with a fragment of the impacted roof tile at the National Science Museum in Ueno, Tokyo while other fragments of the meteorite were exhibited at the Chiba Prefectural Central Museum from 10 November 2020 to 28 February 2021.<\/p>\n\n\n\n
