'Sun breaks tail of comet': Disconnection event observed on Comet ZTF


Space Weather
Wed, 18 Jan 2023 23:32 UTC
Something unusual is happening to the tail of Comet ZTF (C/2022 E3). It's being disconnected. The break is inset in this picture taken by Austrian astrophotographer Michael Jaeger on Jan. 17th:
comet ztf
This is a disconnection event: A piece of Comet ZTF's tail has been pinched off and is being carried away by the solar wind.

Blame space weather. CMEs hitting comets can cause magnetic reconnection in comet tails, sometimes ripping them off entirely. NASA's STEREO-A spacecraft watched this happen to Comet Encke in April 2007: movie.

This month, multiple CMEs have swept past Comet ZTF as a result of surging solar activity. One of them is responsible for the disconnection event.

Soon, we'll get a better look. Comet ZTF is approaching Earth for a close encounter (0.28 AU) on Feb. 1st. Between now and then, the comet's brightness will cross the threshold of naked-eye visibility, possibly peaking at magnitude +5. CME effects will be increasingly visible as the comet approaches. Stay tuned!

Bearizona keepers report that the park has received more than 28 inches of snow at the wildlife park!
More than 2 feet of snow fell over two days across parts of northern Arizona, becoming the 25th largest snow event in Flagstaff history and breaking the record for single-day snow accumulation on Sunday.

The Flagstaff Airport measured 14.8 inches on Sunday, smashing the previous record of 8.9 inches that held for 45 years. As snow continued to fall, accumulation eventually reached 30 inches at the airport by Tuesday morning.

The last time Flagstaff saw a storm of this magnitude was in late January 2021 when officials measured a 33.2-inch snowfall.

The areas impacted by the storm were expansive, said meteorologist Benjamin Peterson, including most areas at elevation above 5,500 feet, stretching from the northern rim of the Grand Canyon east to the White Mountains.

Dead humpback whale beached on assateague island
A dead humpback whale was found beached at the Assateague Island National Seashore early Monday morning.

According to the National Park Service, the 20-foot-long humpback whale was found on the beach on the morning of Jan. 16 in the Maryland Oversand Vehicle Area. The area is currently closed so the whale can be handled safely.

Staff with the NPS contacted the Maryland Department of Natural Resources' Stranding Response Team, and in partnership with the National Aquarium, a necropsy is planned for Tuesday. At the time, there were no obvious signs as to the cause of death.

Officials said heavy machinery will help move the whale to the upper part of the beach, then after the necropsy is performed, it will be moved to the dunes to dry before burial.

Visitors are asked to keep their distance and keep any dogs on a leash. Officials are warning that the carcass will smell for a while but should not be an issue more than 50 yards from the location.

The national capital Delhi logged its eighth cold wave day in January on Wednesday, the most in the month in at least 12 years, according to the India Meteorological Department (IMD).

Several flights and trains were running late due to low visibility, reported news agency ANI.

"Several flights scheduled to depart from Delhi's Indira Gandhi International Airport (IGI) were delayed due to fog, ANI quoted airport authority as saying.

The Sadarjung observatory, Delhi's primary weather station, recorded a minimum temperature of 2.6 degrees Celsius. It was 2.4 degrees Celsius on Tuesday and 1.4 degrees on Monday.

7.0 magnitude earthquake hits Indonesia, sparking tsunami fears

A large earthquake has rocked Indonesia, leading to fears of deadly tsunami waves in the Pacific Ocean.

The Indonesian geophysics agency said that the epicentre of the earthquake's was about 40 miles deep, 88 miles southeast of the small town of Melonguane in the North Sulawesi province.

It is unclear if there have been any deaths or injuries. One local in the regional capital of Manado told Reuters that they had felt the earthquake very strongly for several seconds, and people had run out of buildings, but that no property damage was visiblel.

The Pacific Tsunami Warning Center warned that there was a risk that the earthquake could cause tsunami waves within 300 kilometres of the epicentre, Reuters reported.

But the Indonesian agency said there was no risk of tsunamis.

A 7.5 earthquake hit Sulawesi in 2018 with devastating effect. The tremor and the tsunami that followed killed more than 4,000 people.

The mudslides come amid a series of major winter storms that have walloped California in recent week

A mudslide in a Berkeley Hills neighborhood in Northern California Monday morning forced around 10 homes to evacuate as nearby residents were warned to prepare to leave quickly if needed, fire officials said.

Berkeley police said The Spiral, a short road off Wildcat Canyon Road, and Middlefield Road, north of the Crossways, were both closed.

A mudslide has also closed Wildcat Canyon Road between Sunset and Park Hills roads. Authorities responded to the area around 7 a.m.

Berkeley Fire Battalion Chief Bill Kehoe said the ground was still moving and trees could be heard cracking from the side as of around 9 a.m.

No injuries have been reported so far. Around 20 residents that were affected by the evacuation orders were being assisted by the Red Cross.

Siberia records minus-80 degrees as talk of polar vortex grows

Several weeks after the Christmas Arctic blast, much of the US and Europe have enjoyed record warmth. Recall on Dec. 27, we noted the cold air mass from Siberia that spread across the continental US would dissipate into the new year. So far, this is correct, as three weeks of above-average weather has staved off an energy crisis in the Northern Hemisphere. But just north, in Siberia, temperatures are sinking to near-record lows. And it could only be a matter of time before the giant cold air mass swirling in the North Pole becomes unstable, breaks down, and begins pouring into the US and Europe.

Global warming alarmists who called for an imminent climate disaster last summer are scratching their heads as the rural northern Siberian town of Zhilinda just recorded temperatures of minus-79.8 degrees, according to climatologist Maximiliano Herrera, who tracks extreme temperatures across the globe.

Comment: Disconnected as we are from Earth's rhythms, very few will realize that a 'delayed' winter will disrupt everything from animal migration to agricultural planting and harvest schedules. We are in for a rough ride in the next couple of decades as our accustomed survival patterns disintegrate.
