Strange lights in the sky over Sunnynook have excited UFO fan Robert Edwards but the experience was somewhat unnerving for his wife.

"I think there is probably a logical explanation but I have not been able to find one," Mr Edwards says.

Shortly after spotting two big red-and-orange lights tracking quickly across the sky on Saturday night, he uploaded a video of the sight to Facebook.

The reaction to his clip on Facebook has added to the mystery, he says.

Mr Edwards spotted the lights about 10.30pm.

Facebook postings mention similar sightings in Melbourne about 7pm to 8pm, Te Atatu Peninsula about 8.50pm and Palmerston North later at 2am on Sunday. There were also numerous other online reports about strange lights on Saturday night at Auckland's west coast beaches, Milford and Coatesville.

Some articles suggest they were meteors.

Auckland Airport's tower didn't spot anything on its radar, Mr Edwards says.

And, he's not sure if they were meteors or satellites.

"I have always been an avid UFO believer but I have never seen one myself. It was not a scary experience, it was more fascinating - what can it be?"

But wife Val was a little unnerved having not long ago finished Stephen King's 1987 book Tommyknockers.

The sci-fi book is about an alien spacecraft buried in America's Wild West that releases gas that transforms humans into beings similar to the aliens who were onboard.

Mr Edwards counts himself lucky to spot something unexplained in the night sky.

Early reports of the Te Atatu Peninsula sighting suggested it may have been a meteor because it had light trailing behind it.

Mr Edwards says there was no tail on the objects he saw that travelled quickly across Orion, which many Kiwis know as "the pot".
