Last year, Albertans looking up at the night sky spotted everything from bright balls of light to glowing orbs, and even a "dark sphere the size of a small house."

That's according to the annual Canadian UFO Survey, which said the province saw an increase in reports pertaining to unidentified flying objects in 2015 compared to 2014.

There were 101 UFO sightings reported in Alberta last year and 95 the year before.

The most ever reported happened in 2012 — which according to the Mayan Calendar — was also supposed to be the year the world ended.

"There were 323 reports from Alberta alone," said Chris Rutkowski, a science writer who compiled this year's survey.

"People were spending a lot more time looking and and they were worried that the UFO's were coming. I guess it was sort of end of the world jitters."

The 2015 summary of the survey describes UFO witnesses as "individuals with reasonably good observing capabilities and good judgement."

Rutkowski said they're from all walks of life — pilots, air traffic controllers, and members of the Armed Forces.

"According to some polls, 10 per cent of the Canadian population believe they've seen UFOs. So you're actually in good company if you have seen a UFO."
