February 15, 2016 - ONTARIO, CANADA - Mother Nature has treated residents in the Orangeville area to a
relatively uncommon atmospheric phenomenon only seen a few times every
year.
After a band of snow squalls moved through Dufferin County last night,
the skies cleared to reveal a parhelion — informally nicknamed a sun dog
— near Mono early Saturday morning (Feb. 13).
Local photographer Rose Knott managed to capture an image of the uncommon occurrence early Saturday morning.
"I've never seen a sun dog. It was just so exciting to me," she posted on Facebook. "Just felt so thrilled to capture this."
Sun dogs are formed when sunlight refracts off ice crystals in the
atmosphere, creating bright spots on either side of the sun. In some
cases, a rainbow-shaped halo can be seen connecting these bright pillars
beside the sun.
"It is more the ice crystals high up in the atmosphere that create the
phenomena," Environment Canada meteorologist Geoff Coulson told The
Banner last year. "When those ice crystals reflect the sunlight at a
certain angle, it can form these sun dogs."
Cold air isn't a preamble to a sundog, as Coulson said they could appear
pretty much year round. They usually occur in the morning when the sun
is rising or when it is setting in the evening.
"What you're really looking for is relatively cloud free conditions,"
Coulson said. "To be able to view it, you really would had to be within
sort of the breaks in the flurry activity to actually see the sun and
the phenomena itself." -

Morning 'sun dog' captures attention of residents in Caledon, Ontario

Residents across Caledon were looking to the skies Thursday morning
(Feb. 11) as a unique 'sun dog' cast a spherical glow on the landscape.
"It certainly was a beautiful sight this morning, wasn't it?" local resident, Lori Makarewicz said to The
Enterprise.
"I have never seen one like that before. I almost got frostbite by
standing out in my sandals on the front lawn, didn't want to waste any
time looking for my boots in case I missed it!"
According to Environment Canada meteorologist, Rebecca Wagner, "sun
dogs" which are also classified as parhelion, halos, or "mock suns," are
an optical effect caused by the refraction of sunlight by ice crystals
in the atmosphere.
"In particular this morning we had a very well developed halo around the
sun with two bands with bright spots on either side of the sun, at
about the same elevation," she continued.

While they technically occur any time of the year, sun dogs appear more
vividly in the winter due to the combination of ice crystals in the
atmosphere and the low angle of the sun in the sky - and even still, are
usually only spotted about two to three times a year.
As the sun rises in the sky, the halo diminishes as the angle of the light hitting the ice crystals changing.
Bolton resident, Craig Kellough, spotted the unique optical effect over the North Hill of town.
"I was driving into Bolton around 9 a.m. when I saw this spectacular
scene in the sky surrounding the sun," he said. "I had to pull over and
take as many shots as I could. It was something I had never seen
before."
According to Wagner, with the chilly temperatures and clear skies
predicted for this weekend, there might be another in store for those
who missed Thursday morning's display. -
