WATCH: International Space Station NASA live cam cuts after 'suddenly locking on to mystery glowing UFO'
A UFO hunter claims the ISS camera locked on and zoomed into a “mystery glowing orb”, but after monitoring the ball of light, Nasa cut the live stream from public viewing.
The "Unidentified Flying Object (UFO)" was visible in the distance between the ISS and Earth, according to Scott C Waring, editor of UFO Sightings Daily, before the "camera panned towards it and then zoomed in."
Mr Waring said: "I was watching the space station live cam when I noticed the camera switch to a new camera.
"Then the camera began to swing to the left until it focused on a white oval between it and Earth.
"The object had matched its speed with the space station. The camera then continued to zoom closer and closer, but all we could see was a glowing white oval.
"The vibrate light from the UFO was so powerful that even NASA's new seven million dollar HD cameras could not focus on it."
Mr Waring has contacted NASA to ask for details of what was seen by the ISS camera operator.
He has also posted a video of the "event" to YouTube, in which the light appears so bright it has the appearance of a ring of light around the orb and a cross through it.
Mr Waring said on the video: "Look at the radiance. It almost looks like it has a cross and a bright halo around it. Very unusual and Nasa keeps and eye on it until the go blue screen (video cuts out).
"They are trying to get a good look, but obviously it is too bright.
"Why did NASA turn their camera towards this? Why did NASA want to take a look at this? "What is so extraordinary about it that they wanted to look at it?
"Well the fact is it is a UFO and a glowing object."
Express.co.uk has contacted NASA to ask what, if anything was seen on the camera last Thursday, and awaits a response.
