NASA & Space Weather

Just looked:
1) X-rays from flares observations with Min XSS satellite
2) Kp index ( disturbance to Earth's magnetosphere )
3) Solar Energetic Particles ( SEPs )

Solar Flares were relegated to basically a footnote, with no specific importance implicated.

Jun 9, 2015 New Tool Could Track Space Weather 24 Hours Before Reaching Earth

How do you track 24 hour event horizon when it's just under 9 light minutes to the sun and if you detected it, it would arrive after the event did? At speed of light, the sensor would need to be past Jupiter to do 24 hours. Ask NASA how remote control works on Jupiter orbiting probes.

The light takes minutes, but the wind is variable, up to three days.

As an example, the eruption aimed right at us yesterday is expected to arrive on Thursday.

Is this the new climate space weather thread?

As climate crisis allows new maritime routes to be used, sooty shipping emissions accelerates ice melt and risk to ecosystems. From a [theguardian.com] report:

[examples]

When black carbon, or soot, lands on snow and ice, it dramatically speeds up melting. Dark snow and ice, by absorbing more energy, melts far faster than heat-reflecting white snow, creating a vicious circle of faster warming. Environmentalists warn that the Arctic, which is warming four times faster than the global average, has seen an 85% rise in black carbon from ships between 2015 and 2019, mainly because of the increase in oil tankers and bulk carriers. The particles, which exacerbate respiratory and cardiovascular illness in towns, are short-term but potent climate agents: they represent more than 20% of carbon dioxide equivalent emissions from ships, according to one estimate.

In other news, Amazon drones are crashing in Pendleton, OR, and starting brush fires. They flip over and come down in a fireball!

Unless they are being hit with birdshot pellets there is no sane reason for a flip and fireball. The nav system and flight controller preclude that and airborne battery fires are rare as tesla or Volt fires. Controller fails to off.

Maybe I could've made the link more prominent.

According to Bloomberg, there were five crashes over the course of a four-month period at the company's testing site in Pendleton, Oregon. A crash in May took place after a drone lost its propeller, but Bloomberg says Amazon cleaned up the wreckage before the Federal Aviation Administration could investigate. The following month, a drone's motor shut off as it switched from an upward flight path to flying straight ahead. Two safety features -- one that's supposed to land the drone in this type of situation and another that stabilizes the drone -- both failed. As a result, the drone flipped upside down and made a fiery descent from 160 feet in the air, leading to a brush fire that stretched across 25 acres. It was later put out by the local fire department.

No you were specific enough. The actual Bloomberg article is different that your blurb.

The motor controller is a 3 phase H Bridge so if one phase fails the other 2 bridges burn out in rapid sucession unless they so overbuilt the power circuits that locked rotor conditions do not result in immediate over temp junction failures, OR, they are running brushed series DC which will overspeed on failure of the power circuits. And you have one set of these for each motor, once again unless they are doing massive shortcuts, because motor control gets squirrelly running two multiphase motors off one ESC. I could see the fireball scenario on over specced controllers or battery shorted conditions. Just like Volts catching fire when they get punctured and flipped over then sit in an impound lot for a week.

Something don't pass the sniff test. And they fly like aerioplanes, you dont switch from flight regimen to another, you gradually change it.

This might be Space Weather since it was caused by change in the speed of the Earth's rotation.

Massive earthquake swarm driven by magmatic intrusion at the Bransfield Strait, Antarctica
Abstract
An earthquake swarm affected the Bransfield Strait, Antarctica, a unique rift basin in transition from intra-arc rifting to ocean spreading. The swarm, counting ~85,000 volcano-tectonic earthquakes since August 2020, is located close to the Orca submarine volcano, previously considered inactive. Simultaneously, geodetic data reported up to ~11 cm northwestward displacement over King George Island.

Melting Ice Caps May Not Shut Down Ocean Current (phys.org)
Climate scientists count the Atlantic Meridional Overturning Circulation (or AMOC) among the biggest tipping points on the way to a planetary climate disaster. The Atlantic Ocean current acts like a conveyor belt carrying warm tropical surface water north and cooler, heavier deeper water south. [...] In a study published [...] in the journal Nature Climate Change, He and Oregon State University paleoclimatologist Peter Clark describe a new model simulation that matches the warmth of the last 10,000 years. And they did it by doing away with the trigger most scientists believe stalls or shuts down the AMOC.
....
"Without the freshwater coming in making the AMOC slow down in the model, we get a simulation with much better, lasting agreement with the temperature data from the climate record," He says. "The important result is that the AMOC appears to be less sensitive to freshwater forcing than has long been thought, according to both the data and model." [...] The widespread consequences of a drastic weakening of the AMOC include rapid sea-level rise on the eastern coast of North America, cooling over Europe that could disrupt agriculture, a parched Amazon rainforest and disruption of Asian monsoons. The new modeling study anticipates a much smaller reduction in AMOC strength, but that doesn't rule out abrupt change.

So, the Beaufort Gyre may be toothless.
