The Hong Kong Observatory says suspected UFO sightings near Tai Lam Tunnel, as well as in Wanchai and Happy Valley, were probably street lamps. The sightings occurred two nights ago during a lightning storm. The Observatory said it received a number of calls. The chairwoman of the Hong Kong UFO Club, Moon Fong, said similar reports were also made to its website. The Observatory said a record 10,000 lightning strikes were recorded within an hour that night. A scientific officer at the Observatory, W C Woo, said they'd investigated the reported sightings and believe, in most cases, they were merely street lamps.
