Examiner.com's UFO expert Roger Marsh caught wind of a MUFON report I missed. Apparently, a McAllen, Texan resident witnessed a UFO that, while stationary in the sky, kept distorting its shape and increasing and shrinking in size. Apparently, it was similar to a different McAllen UFO sighting (video posted below), which to me seems like a typical orb sighting. The witness speculated that it could be a drone. From the Examiner story:
"It reflected the setting sunlight (still fairly bright and white at the time) but also glowed and alternately sharpened and slightly blurred in appearance," the witness stated. "The day was dry and clear, no clouds. I was only able to watch the event out my car window. My wife also saw the object and was disturbed by its appearance as something not easily explainable."
The witness pulled into a cosmetology school parking lot for a better look.
"By that time, the object had disappeared. The last look I had of it, it appeared to be shrinking in size and decreasing in size and brightness. This sounds like an aircraft moving into the distance, but the object did not move. I have observed aircraft on a straight line also appearing to hover, but this object did not look like an aircraft."
The witness speculated on what the object could have been.
"I would say it was some kind of large, drone-like object (maybe 50 feet in length), but the odd blurring of its surface edges, followed by a glowing and then sharpening of its outlines, was very odd. It was very distinct and very bright and then it disappeared."
What the object looked like, according to the witness:
