It appears to be an upside down rainbow, but it's not formed in the same way as a rainbow. It's called a circumzenithal arc and is caused by the refraction of sunlight through ice crystals in the upper atmosphere.
It's similar to a halo around the sun or moon.
To see a circumzenithal arc, the sun has to be at about 22 degrees above the horizon. This happens more often in colder months when the sun's angle is lower and we are more likely to see a mostly clear sky with cirrus clouds.

A highway camera in Montana shows near white-out conditions near Sweet Grass, Mont., at 7:50 p.m. Wednesday
A winter storm information alert was issued Wednesday evening, warning travellers to turn back if they're headed to the Canada-U.S. border crossing at Coutts, Alta. and Sweet Grass, Mont.
The border crossing was closed at 6:30 p.m. Highway 4 remains open in Canada, but travel is not recommended, while the I-15 is closed from the border to Shelby, Mont., where multiple vehicles have slid off the highway.
"If you come to U.S. Customs, they're turning you back," said Lori Rolfe, the Village of Coutts' chief administrative officer. "We have lots of snow and lots of blowing so visibility is not great."
Rolfe said the closure was extremely unusual — the last time she recalls a similar incident was in 2000.
The jellyfish washed ashore on Tuesday (November 26) were of the Aurelia aurita jellyfish, commonly known as 'moon jelly' and root-mouth jellyfish species.
Their on-shore appearance is bad for both beachgoers and the jellyfish themselves. Jellyfish start dying the moment they hit the beach and can still sting people if handled.

The truly mesmerizing footage was uploaded to YouTube this week by marine biologist Vanessa Bézy; using a drone, she captured the turtle swarm swimming in the Ostional National Wildlife Refuge back in November 2016.
"Everybody I've shown this video has an emotional response," Bézy says. "I immediately knew there was something special going on... To this day, I'm still blown away by the video."
The city's Civil Defence said 169 mm of rain fell in 3 hours during the morning of 26 November. The monthly average for November is 106.5mm. Civil Defence Salvador added that Liberdade and São Caetano neighbourhoods recorded more than 250mm in 3 hours. Civil Defence had issued timely warnings for the heavy rain, including the sounding of sirens in some districts.
The torrential rain caused flooding and landslides across the city. Civil Defence reported more than 300 incidents. Streets were flooded and around 100 homes damaged. Almost 300 people were evacuated. However, no casualties were reported.
Parts of the city have a high risk of landslides. The government of Salvador recently embarked on a series of risk prevention projects across the city, securing slopes and installing geomats.
The girl, identified only as Ling Ling, was attacked while walking alone on a small rural path between a cornfield and woodland in Quyang county, Hebei province, last Thursday, Shanghai-based news site Thepaper.cn reported on Tuesday.
She cried out as the dogs lunged for her neck and passing pupils ran to the school for help, the Yanzhou Metropolis Daily reported.
Ling Ling's older sister came running and tried to drive the dogs off with rocks but failed and went home to get their parents, the newspaper report said.
The parents drove the animals away but the girl later died of her wounds in hospital.
"Both dogs were big. They jumped on and bit the girl's neck. Her neck was almost severed and her head had wounds, too," the newspaper quoted a villager as saying. "It's so horrific."
Weather watches, warnings and alerts were posted across much of the western half of the nation after a storm that had been a "bomb cyclone" marched westward from the California coast, AccuWeather reported.
Hundreds of stranded cars were removed from Interstate 5 headed north from California into Oregon in the aftermath of the storm that dumped snow and created whiteout conditions on both sides of the California-Oregon border.
As the skies cleared Wednesday, drivers reported being stuck for 17 or more hours in blizzard conditions and some spent the night in their vehicles.
Farther south, winter storm warnings were in effect for the mountains near Los Angeles into early Friday with 6 to 12 inches of snow forecast for most mountains, except 12 to 24 inches for the San Gabriels, the National Weather Service in Los Angeles warned.

This happened around 16 hours yesterday, lightning struck a kraal housing cattle belonging to Malebekwa Mbulai (91).
Mr. Mbulai, who was emotional charged said he wondered how lightning struck the animals that were under a tree which was however not affected at all.
He said the incident was strange considering the fact that the meat did not turn dark as usually is the case in lightning incidents.
The 91-year-old man said almost all the animals that died were oxen, which are used for transportation and ploughing.

A jet passes snow-covered cars parked at Denver International Airport on November 26, 2019 in Denver, Colorado. Flights were delayed and rescheduled due to a winter storm that dropped nearly a foot of snow in the city.
The storm was heading to South Dakota, Iowa, Michigan, Minnesota and Wisconsin, while a "bomb cyclone" weather phenomenon began toppling trees, knocking out power and dumping snow as it barreled into California and Oregon — making for a double whammy of early wintry weather.
Authorities on both sides of the California-Oregon border reported numerous crashes and closed roads. The National Weather Service urged people to wait to travel for the holiday until the weather improves.
At Denver International Airport, about 10 inches (25 centimeters) of snow mixed with winds that limited visibility prompted the cancellation of about 30 percent of the airport's average daily 1,600 flights.
