HOURS after a meteor exploded over Russia and injured more than 1000 people and an asteroid passed relatively close to Earth, residents in California reported seeing an unusual flash of light over the San Francisco Bay area that left many startled and thrilled.
Based on reports, the light streaking in the Northern California sky was a sporadic meteor, or fireball, and not a major event, said Mike Hankey, operations manager for the American Meteor Society in Genesee, New York. The group recorded at least 35 reports of the event, he said.
"Fireballs happen every single night, all around the world," he said.
Experts say smaller meteorites hit Earth five to 10 times a year but chances of a large meteor passing, such as the one that streaked over Chelyabinsk, Russia, are much rarer. Another meteor landed in the Bay Area in October and caused a loud sonic boom, a sound that could have been from the meteor travelling faster than the speed of sound, officials said at the time.

Another meteor that exploded April 22 was seen over a large part of Northern California and Nevada.
On Friday, the Chabot Space and Science Centre in Oakland also reported receiving calls describing what appeared to be a fireball flying west around 8pm local time.
Jonathan Braidman, an instructor at the centre, described the object based off reports as likely being a small piece of an asteroid that "somehow" got on a collision course with Earth.
"This is a very common occurrence," Braidman said. "What is uncommon is that it's so close to where people are living."
Bay Area media outlets reported the fireball was reported seen from an area stretching from Gilroy, about 130 kilometres south of San Francisco, to Sacramento, about 145 kilometres to the northeast.
One viewer told television station NBC11 the object was bluish in colour and appeared to be heading straight to the ground.
San Leandro resident Krizstofer Loid told KTVU-TV that he was sitting on a lawn chair in the backyard of his home when he saw the object.

"I saw, like, a blue streak from the sky coming down. I thought it was fireworks, but I didn't hear any sounds," he said.
The centre's large telescopes did not pick up the object during a stargazing event, astronomer Gerald McKeegan told KGO-TV.
"The media attention on the Russian thing got people's attention, so they're more likely to notice things in the sky," Hankey said.
While Friday night's fireball received a lot of attention in the San Francisco Bay area, Braidman notes that about 15,000 tons of debris from asteroids enter the earth's atmosphere every year.
"Usually these things break up into small pieces and are difficult to find," he said.
The news of North America seeing lights comes as Cuba also apparently experienced a phenomenon similar to but smaller than the meteorite that hit Russia.

Residents described a bright light in the sky and a loud explosion that shook windows and walls.
There were no reports of any injuries or damage such as those caused by the Russia meteorite.
In a video from a state TV newscast posted on the website CubaSi late Friday, unidentified residents of the central city of Rodas, near Cienfuegos, said the explosion was impressive.
"On Tuesday we left home to fish around five in the afternoon, and around 8:00 we saw a light in the heavens and then a big ball of fire, bigger than the sun," one local man said in the video.
"My home shook completely," said a woman. "I had never heard such a strange thing."
Marcos Rodriguez, whom the video identified as a specialist in anthropology, said all signs point to a meteorite.
