Alejandro Molla, a computer scientist from Spain, was filming an electrical storm that swept across the sky over northern Alicante. On closer inspection, what looks like a silvery flying saucer appear to dart around the top right hand corner of the footage.
Since the recording Spanish news outlet Agencia 6 (A6) says it has been inundated with requests from UFO and weather enthusiasts since sharing the clip online.
In addition to public interest, A6 claims it has been contacted by NASA, who asked for the original clip in order to investigate it further.
According to A6, a similar sighting was reported by NASA in skies over Wisconsin last July.
NASA would therefore be seriously interested in learning more about the apparent sighting.
Thunder and lightening reportedly woke Mr Molla up in the early hours of Saturday morning.
He quickly started to record the storm in an attempt to catch it in its might.
In doing so, the Spaniard inadvertently captured the orb that span out of control at a fast pace.
The University of Alicante then analysed the film – and spotted “something weird”, Alejandro claims.
