A Canadian woman was left scratching her head at the sight of a rather sizeable disk-shaped UFO spotted hovering over the city of Edmonton. According to her account submitted to the National UFO Reporting Center, the perplexing anomaly was observed earlier this month by the unnamed witness who recalled that "I saw a big black circle in the sky over the horizon and stopped to watch it when I realized it wasn't a regular aircraft." Estimating that the anomaly was "the size of a bus or larger," the witness noted that "it was moving around in a way I couldn't understand, like it was undulating."

Her suspicion there was something unusual about the object compelled the witness to capture the wondrous scene with her cell phone. In the footage, she can be heard marveling "what is that" as she watched the weird UFO overhead. While the witness first thought the oddity could simply be a balloon, she questioned that assessment when "it suddenly accelerated quickly across the sky, then it went way higher up closer to the clouds" where she noticed a similar object "above it even further into the atmosphere."

After about two minutes, the pair of UFOs drifted up into the clouds and vanished from sight, leaving the witness wondering what she had just seen. To that end, as one might imagine, some have suggested that the objects could have been otherworldly visitors because of how strangely they moved through the sky. Meanwhile, more skeptical viewers posit that the UFOs may have merely been, as the witness initially suspected, errant balloons. What do you think she filmed over Edmonton?
