Odd, lights glowing and flickering in the early morning sky above Cape Coral on Jan. 27 had many Florida residents reporting possible UFOs to their local NBC affiliate.
"They were small lights that hovered over the water...and then they disappeared," Pete Maccio told the TV station.
Nearly a week later, nobody is quite sure what they saw.
Watch the NBC-2 report on the Cape Coral UFOs
Cape Coral, located on the Gulf of Mexico side of The Sunshine State, is known for having more miles of canals than any other city in the world. Now it's also known for UFOs.
Theories on what the unusual lights might be range from water reflections in the sky to aliens to another more probable explanation, and one very often mistaken for UFOs: sky lanterns.
"We reached out to the MUFON organization, the Mutual UFO Network, which tracks suspicious spottings," NBC-2's Steve Campion reported.
"They told us many of the recent reports filed with them across the state could be explained by a sky lantern. The increasingly popular contraption uses hot air to float high into the sky," he said.
In November, FOX-4, WFTX-TV, received several phone calls from eyewitnesses who saw unexplained lights over Cape Coral. One person said, "They were actually those Chinese lanterns you light up like a balloon and it floats up and then when they go out, they fall to the ground. That's exactly what they were."
The most recent sightings over Cape Coral have brought out opinions from those who completely disagree with the sky lantern idea.
Commenting in International Business Times, Teresa Thornton wrote: "Sky lanterns!!! That is the most ridiculous explanation for these lights yet, second only to swamp gas. Lanterns are balloons and these lights don't act like balloons -- even if they were tethered, they would be bouncing around independently in the wind or breezes over the water.
"Notice how they stay in the same pattern, not rising or falling. ... I'm sorry, but MUFON HAS NOT explained this away."
And if you can't get enough of these sky lanterns, feast your eyes on this.
On June 2, 2012, 12,740 lanterns were released into the air over Iasi, Romania. This incredible event claimed the Guinness World Record for "Most Sky Lanterns Flown Simultaneously."
Looking at the following video, it's easy to see why these objects are so often referred to as UFOs
Lanterns are among the many things that people mistake for truly unexplained objects. Here are some more:
This is a composite image of how three alleged UFOs maneuvered about in the sky over Melbourne, Australia, in early February, 2013. The final verdict isn't in yet on whether they're birds, aircraft, balloons, bugs or something truly unidentified.
These candle-lit Chinese lanterns can rise high into the sky and are often mistaken for UFOs.
On Dec. 20, 2012, a bright, circular object (pictured at the top of this composite image) was videotaped exploding in the skies above Sacramento, Calif. It wasn't immediately identified, resulting in speculation that it was either an alien spacecraft, military top secret weapon, runaway planet, North Korean satellite, among others. Within a short period of time, it became apparent that this was a weather balloon. The bottom part of this image shows such a balloon as it ascended over Tampa Bay, Fla., on July 2, 2012, and exploded in an identical manner as the Sacramento object, probably much to the dismay of all true ET believers out there.
This is a composite of images shot by two eyewitnesses of a boomerang-shaped UFO they reported seeing over their Burbank, Calif., home on Oct. 5, 2012. Mutual UFO Network photo/video analyst Marc Dantonio concluded the object was likely "a balloon, floating on the wind that has collapsed in half."
This four-image series of lights in the sky was recorded over Warren, Mich., on Jan. 10, 2013. The lights were seen changing into several patterns. The most logical explanation for these types of UFOs is a series of balloons or lanterns.
This composite image shows four different times that alleged UFO were photographed above Earth by either space shuttles or the International Space Station. The big question is whether or not they are truly unidentified objects or if they are more likely reflections from spacecraft windows, meteors or fast-moving spacecraft-generated debris.
What appear to be pink-red UFOs are actually lens flares from the Google Earth street view camera as it snapped images in Texas (left) and New Mexico (right).

On the night of Sept. 28, 2012, a group of strange-looking lights appeared in the sky near Cincinnati, Ohio. First there was one, then, two, then three lights, slowly descending. It turns out, however, that these lights were originating from a group of skydivers performing a pyrotechnics jump at the La Salle High School homecoming event.
Some UFO sightings may be due to a natural phenomenon known as sprites, like this one shown from 2006. "Lightning from [a] thunderstorm excites the electric field above, producing a flash of light called a sprite," said geophysicist Colin Price.
Clouds: Saucer-shaped or "lenticular" clouds that form at high altitudes have been confused with UFOs.
Blimps or advertising balloons: These can look like flying saucers from some angles, especially at night.
On June 19th the Swedish-based diving company Ocean Explorer discovered something they've never quite seen before. They were exploring in the Baltic Sea between Sweden and Finland looking for sunken treasures when a very unusual image suddenly appeared on the sonar. A 197 feet diameter cylinder shaped object was discovered at the depth of approximately 275 feet which resembles the Millennium Falcon from the movie Star Wars.
An image released on June 15, 2012, shows a close-up view of the unidentified object sitting on the bottom of the Baltic Sea.

Pictured is a quad copter -- a deliberately manufactured UFO created by special effects wizard Marc Dantonio for a National Geographic special, "The Truth Behind: UFOs," which aired in December 2011. On the left is what the small device looks like resting on the ground, measuring 4 feet in circumference. At right, is how it appeared behind a tree in the night sky.
In February of 2012, this fireball was captured by a Texas police chief's A dashboard camera. F.A.A. say this was probably a meteor, falling to Earth. .
Meteors: Space debris can create a spectacular light show when it burns through the Earth's atmosphere, and sometimes reported as UFOs.
Civilian or military aircraft: Planes can look mysterious at night or in certain light conditions, thus confusing an observer.
