If you did, you spotted an atmospheric optical phenomenon known as a 22-degree halo.

What are sun halos?

Earthsky.org explains it very simply: "Halos are a sign of high thin cirrus clouds drifting 20,000 feet or more above our heads."

Spectacular stronger-than-usual explosion at Stromboli volcano, Italy

Eruption of Stromboli volcano

Eruption of Stromboli volcano this morning
Another stronger-than-usual explosion occurred at the volcano minutes ago at 10:17 local time our correspondents on the island informed us.
From the village, a spectacular ash plume rising several 100 m above the summit could be seen. Soon after the eruption, moderately strong ash rain of small lapilli set in, covering all surfaces.

The color of most particles, up to a few mm in size, was mostly brown to reddish brown, described as "earthy". This could mean that most of the ejected material might be from older lava rocks in the summit craters or inside the vent, from collapsed parts of the craters or conduits. However, a small amount of lighter pumice was also present in the ash, probably representing a batch of fresh magma that had driven the explosion.

Last Tuesday (10 Nov), Stromboli also produced a significant above-average eruption. Such events are nothing unusual on the volcano and occur from time to time, but rarely more frequently than every few months or so. Whether this recent increase is a coincidence or hinting at a more pronounced change in activity level or type is currently unknown.

A webcam at the summit of Mauna Loa shows a dusting of snow at at Mokuʻāweoweo caldera.
The summits of Mauna Kea and Mauna Loa got a light snowcap Sunday morning.

Cold temperatures aloft combined with some moisture to give the state's two tallest mountains a dusting of snow overnight.

Web cams near the summits of both mountains on the Big Island showed a thin coat of snow on the ground.

The National Weather Service said temperatures were cold enough Sunday morning to support more snow showers, but no significant accumulations were expected.

Record-breaking winds shake ground, send debris flying in Ontario

winds
Widespread damaging winds swept through Ontario Sunday, with hurricane force gusts strong enough to cause ground shaking in Toronto.

Heavy rain and fierce winds whipped through much of southern Ontario Sunday, courtesy of a potent Colorado low with widespread impact across the province.

Record-breaking winds were reported throughout the day, including a gust of 118 km/h at Toronto Island and an impressive 141 km/h gust in St. Catharines. Those were both strong enough to set new all-time records for the month of November.

Winter is coming: Snow, rain send temperatures plunging across Pakistan

Snowfall in Gilgit, Chitral

The first snow, and rainfall in multiple parts of Pakistan have signaled the arrival of winter in the country.

Northern areas such as Chitral, Abbottabad, parts of Azad Jammu and Kashmir and Nathiagali experienced the season's first snowfall along with cool winds.

Following this, the temperatures dropped, forcing residents to take out their jackets, sweaters and blankets.

In Chitral, over three feet of snow was recorded in the last two days. Due to this, multiple roads to and from the city were blocked. Ghizar experienced a similar situation.

A typhoon is swelling rivers and flooded low-lying areas as it passes over the storm-battered northeast Philippines, where rescuers are working to help people flee the rising waters

A typhoon swelled rivers and flooded low-lying areas as it passed over the storm-battered northeastern Philippines, where rescuers worked Thursday to help people flee the rising waters.

Rescue officials said at least three people had been killed — two in Camarines Norte province and another in the town of Tanay in Rizal province.

Typhoon Vamco passed north of Manila between Bulacan and Pampanga provinces, toppling trees and knocking out power. Officials said earlier that nearly 200,000 people had been evacuated, some forcibly, from vulnerable coastal and low-lying areas.

Rescuers and residents ride in rubber boats amid rising floodwaters in a submerged village, as Typhoon Vamco hits the Philippines
Thick mud and debris have coated many villages around the Philippine capital after a typhoon caused extensive flooding that sent people fleeing to their roofs and killed at least 39 people.

Thousands of people have been rescued by Friday, though waters have mostly receded. The military was rescuing people in places where waters remained high.

Amphibious assault vehicles, usually used in counter-insurgency operations, were deployed for the rescue work, military chief of staff General Gilbert Gapay said in an emergency meeting with disaster-response officials.

"We'll continue to look for the missing, help in damage assessment," Gapay said. He reported 39 deaths and 32 other people missing.


Typhoon Vamco passed north of Manila between Bulacan and Pampanga provinces overnight Wednesday and early Thursday, toppling power poles and trees and damaging homes.

More than 350,000 people had been evacuated to safety, mainly residents fleeing vulnerable coastal and low-lying areas before the typhoon hit. Philippine National Police said more than 100,000 people had been rescued, including 41,000 in the capital region.

At least 3.8 million households lost power in metropolitan Manila and outlying provinces,
but crews have restored electricity in many areas and power was expected to be fully restored in about three days. Government offices were closed and classes suspended for public schools on Friday.

Vamco hit the Philippines on the heels of Typhoon Goni, one of the strongest typhoons in the world this year, which left more than 30 people dead or missing and damaged or destroyed 270,000 houses. Tens of thousands of people remain displaced.

The Philippines is hit by about 20 typhoons and tropical storms each year and also had active seismic faults and volcanoes, making it one of the world's most disaster-prone countries.

67 Dead, 12 Missing As Typhoon Vamco Rips Through Philippines

Twenty-two fatalities were recorded in Cagayan, 17 in southern Luzon provinces, eight in Metro Manila, and 20 in two other regions.

Houses are submerged in flooded areas in Cagayan valley region, northern Philippines on November 14, 2020.

Houses are submerged in flooded areas in Cagayan valley region, northern Philippines on November 14, 2020.
The number of deaths in the deadliest cyclone to hit the Philippines this year has climbed to 67, with 12 people still missing, the national disaster management agency said on Sunday.

President Rodrigo Duterte was scheduled to fly to the northern Tuguegarao province later in the day to assess the situation in Cagayan Valley region, which was heavily flooded after Typhoon Vamco dumped rain over swathes of the main Luzon island, including the capital, metropolitan Manila.

Twenty-two fatalities were recorded in Cagayan, 17 in southern Luzon provinces, eight in Metro Manila, and 20 in two other regions, said disaster agency spokesman Mark Timbal.

Twenty-one people were injured, he said.


Many areas in Cagayan, a rice- and corn-producing region of 1.2 million people, remained submerged as of Sunday, according to media reports.

Heavy flooding, caused by the accumulated effects of previous weather disturbances, as well as water from a dam and higher plains affected thousands of families, some of whom had fled to rooftops to escape two-storey high floods.

The damage to agricultural commodities due to floods was initially pegged at 1.2 billion pesos ($25 million), while infrastructure damage was estimated at 470 million pesos, Timbal said.

There has been a huge increase in attacks on children by dogs
The toll is up 352 on 2018 and 52 per cent higher than a decade ago, with animal welfare experts blaming irresponsible owners and a flawed Dangerous Dogs Act

Dog attacks hit a record high last year with a disturbing 1,700 kids savaged.

Of 8,859 victims across England who needed hospital treatment, 37 were babies, 603 were aged one to four and 538 were five to nine.

The toll is up 352 on 2018 and 52 per cent higher than a decade ago.

'Severe cyclones' have been leaving giant holes in Antarctic ice

The 2017 polynya.
It appeared in 1973, seemingly out of nowhere: a hole in the sea ice off the coast of Antarctica. But this was no ordinary hole. It was so big it could swallow California.

The mysterious opening remained in place for the following three winters. Then it seemed to largely disappear before emerging again in 2017, with a giant maw the size of Maine.

This giant hole with a sometimes state-sized appetite is what's called a polynya - an area of open water surrounded by sea ice, kind of like the opposite of an iceberg.
