When several callers phoned into San Diego's NBC News affiliate April 28, the station captured this unusual colorful grouping of aerial lights over San Ysidro, close to the U.S.-Mexico border.

"Some said they appeared to be red, blue, and green and kept flashing and changing colors. Some who saw them say the lights didn't seem to move, like those on a plane or a drone," NBC 7 San Diego reported.

According to the station, "We put in calls to the military here to see if they could identify what these were. So far, no response."

It wouldn't be the first time that UFOs had been reported to local military bases around San Diego. Previously classified government documents under the Air Force's former Project Blue Book UFO study show how San Diego's military has seen its fair share of UFO reports.

Regarding this most recent case of odd lights in the sky, the TV station itself has stopped responding, after UFO researchers and The Huffington Post called, asking for details of the event.

A reporter, who said she was instructed not to give her name, told HuffPost that the station management didn't want any of their photographers interviewed or giving out information on the matter.
