Authorities are alarmed by reports and photos of mysterious lights, the Indian Express reports:

One evening a little over a fortnight ago, a mysterious illuminated object appeared without warning in the dark sky above the world’s largest oil refinery in Jamnagar, Gujarat. It circled over the complex before disappearing just as suddenly as it had appeared.

Three days later, the object returned. (Read more…) This time, the process cameras at the Reliance Industries Ltd refinery managed to take a few pictures of the object. It was bright and spherical. RIL has reported the sightings to the government. The Air Force, Navy and Coast Guard have been put on alert, and the defense ministry is beefing up security for the refinery, sources said.

RIL executive director P.M.S. Prasad wrote to Petroleum Minister M. Veerappa Moily: “One unidentified bright object, perceived to be of the size of a volleyball, was seen hovering. It was seen to circle four times before disappearing.”
