# REPORT OF AN ABNORMAL PHENOMENON Jan. 26, 1949. CMO., Tokyo. A telegram was received from the Takayama Weather Station (3609'N, 137015'E) stating as follows: At about 7.40 p.m. on 25th, a remarkable glow was experienced to the southeast of this station. This glow moved southwestwards and then disappeared followed by a sound like thunder after a few minutes. This sound was rather loud in the vicinity of Osaka Town near this station. According to a report from Miya Village, the glow appeared there almost overhead, a few minutes later, a sound resembling to thunder was heard from the south. Summing up the reports by eye-witnesses, this phenomenon might be the explosion of a meteor. Also at Gifu, a glow was seen to the north-north-east at about the same instance as above, while in the Nagoya District Central Meteorological Observatory, no such a phenomenon was observed.
