The pictures circulating Twitter are of a sky covered in a sheet of clouds excepting one hole emitting what appears to be a strange blue glow.
"So the @WhiteHouse wants you to believe what happened over the skies of Stockton yesterday was a 'cloud formation' ? GTFOH #iKnowWhatiSaw," tweeted @CaPtDCharles
"Is that the wormhole from Donnie Darko?" wondered @NGC.
Unfortunately, for those eager to meet some interplanetary visitors, the phenomenon was a natural one. It was likely a "hole-punch cloud" that is usually caused by a plane passing through the cloud bank. The blue glow was most likely from cloud iridescence, a phenomenon caused by thin clouds with similarly sized water droplets diffracting light.
