A series of unidentified flying objects have been reported in the night skies of at least two U.S. cities in the last week.
The collection of strange round lights recorded by mesmerized witnesses show them flying in similar formation, most recently in San Francisco while just days after spotted in New York.
'I wasnít sure if at first if it was another Tequila hazed mirage, but myself and a few bystanders were all in complete awe at the lights we saw on Valencia,' Sunday morning's witness Enrique Barrios told Mission Mission of the California sighting.

Bizarre spotting: Recorded in San Francisco on Sunday morning was this collection of small golden lights seen by several witnesses moving in the sky just left of this lamp post
Unusual sight: Zoomed into the unusual sight, five small lights are seen forming into a V or triangle shape baffling witnesses as well as scientific experts on what they are
The bizarre scene yet to be explained by local authorities or scientific experts comes six days after a similar sighting on the East Coast in Brooklyn while seen hovering over the neighbourhood of Prospect Heights.
In a similar video recording taken from the ground, a witness captures the golden globes moving in similar formation until one disappears - much like a couple do in San Francisco.

Many have already linked both sightings to the encroaching so-called Dooms Day less than two weeks away on December 21, thanks to the Mayan calendarís end.
'Itís not a planet, itís not a constellation, itís not meteors, itís not the moon,' Bing Quock, assistant director of the Morrison Planetarium at the California Academy of Sciences told CBS5 after viewing the San Francisco footage.
Asked if he believes they could be extra-terrestrial spaceships, he answers: 'That would not be my first guess, no.'
East Coast: Six days earlier in Brooklyn, New York these three lights were recorded moving in a similar fashion while the highest light on the left is seen moving in toward the other two
Formations: Eventually the three lights stack up like a triangle until the top light fades away
Like others, Mr Barrios included, he notes their possibility of being balloons fixed with lights, much like a Chinese lantern.
'In the beginning they looked like flying candles,' Mr Barrios told CBS before adding, 'and then afterwards they started making formations, triangular formations.'
That change in direction is what left him sceptical on their of-this-world identity.
As LiveScience notes, if they were paper lanterns - their fixed candles creating heat allowing them to float away - they could travel in a similar motion, as captured on camera, while sharing the same air current.
San Francisco's sighting was also after the first night of Hanukkah.
But perhaps those disbelieves had to be there, as Mr Barrios resolves with his own assessment:
'I am 100 per cent sure this was a UFO Ö you folks be the judge.'
