Unusual light appears in cloud formation in sky over Indiana

UFOs...a government project...natural phenomena?

That's the question after video posted online shows a strange light appearing from within a cloud in the sky over Greenwood , Indiana.

The video was posted to YouTube by QuadeM13 on June 12.

It shows what appears to be e a spotlight shining from inside of a cloud formation.

The website Inquisitr.com, says the light may be related to a U.S. High Frequency Active Auroral Research Program (HAARP) experiment.

CloudAppreciationSociety.org says the lights could be as a result of an optical effect known as 'mock sun.'

Still unsure - watch the video yourself and decide: https://www.youtube.com/watch?t=48&v=CPk0mKVnnCs
