Reporter in the sighting area also probably contributed to the visual sighting. The temperature inversion which probably produced the mirage was probably responsible for the targets on radar. The objects which were actually responsible for those sightings are unidentified due to a lack of information.

It is concluded that a temperature inversion with the associated mirage effects both visual and radar is the cause of this sighting.
