As KSAZ‘s Andrea Robinson delivered a traffic update Thursday morning, a mysterious orb of bright light appeared in a live shot of a Phoenix highway.

The flash of light, reminiscent of an explosion, comes just days before the 15th anniversary of the famous “Phoenix Lights” incident, in which a series of lights were observed in the skies over Arizona.

KSAZ checked with local utilities companies to see if perhaps a transformer had blown, but there were no reports of such an explosion.

The station has asked viewers to share any information they may have about the flash on Facebook and Twitter. So far, there is no evidence that the flash was caused by visitors from outer space (there is also no evidence that is was not caused by aliens). Video inside…

Elsewhere on the dial, Phoenix ABC-affiliate KNXV recently reported on home video that shows a V-shaped series of lights hovering above Arizona (video here).
