In yet another incident of UFO sighting, a round object was spotted hovering over the skies of Calgary, Canada. The unusual sighting was made on 20 June. 

The weird sighting was witnessed by YouTube user unicusCDN, who posted it on the video-sharing website.

"This is an intriguing UFO. It partly cloaks several times in the video. Do not assume that its changing shape. Big misconception. Its just the cloak activates when their is a blue background. Notice the photo below, the UFO is in a white cloud, however the top 20% of the UFO is missing and there is a partial blue background on that part. Cloud orbs cloak like this when seen up close," reported UFO sighting daily.

Similar sightings have been reported in the past as well. A mysterious hole in the cloud was reported on 9 May over Stockton, Northern California. Images of the strange object left people wondering the reasons for such a phenomenon, reported Daily Mail.

Many people shared their thoughts on social networking sites such as Facebook, Twitter and Instagram on what appeared to be a strange, bright hole in the undisturbed clouds over Stockton.

The phenomenon was explained by National Oceanic and Atmospheric Administration (NOAA) as the "hole punch cloud", which is formed when the cloud temperature drops below freezing point, forming ice crystals. The evaporating crystals leave behind a hole in the cloud.

Another similar event was reported in Northern California in 2010 as well.

Though these types of natural formations are common in these parts of the world, experts disagree, stating that Stockton has been comparatively warmer this year.

In yet another UFO sighting, crew from an Australian TV production captured two UFOs flying over Queenstown, New Zealand. The sighting was captured while shooting the seventh season of "Colour In Your Life" series.

The video of the UFO, uploaded by the TV programme, had captured worldwide attention through social media portals. The sightings were captured on 3 May, while filming the first episode of the series. But it was only when the crew started reviewing the edited footage, they noticed two mysterious objects flying overhead.
