Hurricane Trump, Category 5 Disaster…


Behemoth Hurricane Dorian is something of a mystery to Donald Trump. Its anyone’s guess if he can spell hurricane, let alone fathom how they form or what they’re capable of. Heading into the weekend a flicker of presidential duty saw Trump cancel travel plans to Poland and meeting with Ukrainian President Volodymyr Zelenisky to monitor Dorian at home. Home being Camp David – no wait, seems he left Camp David on Marine One to play golf at his course in Sterling, Virginia. Trump crony, Senator Rick Scott of Florida told Fox News –

“We got updates while I was there,” Scott said. “He got updates, I know he played golf yesterday and got updates while he was playing golf.”

Today Trump said –

“We don’t even know what’s coming at us. All we know is it’s possibly the biggest. I have — I’m not sure that I’ve ever even heard of a Category 5. I knew it existed. And I’ve seen some Category 4’s — you don’t even see them that much,” Trump said at a briefing with officials at FEMA’s headquarters in Washington, DC.

“But a Category 5 is something that — I don’t know that I’ve ever even heard the term other than I know it’s there. That’s the ultimate, and that’s what we have unfortunately,” he added, in reference to Hurricane Dorian.

Levels of Trumps’ flippant ignorance are staggering.  Dorian is the 4th category 5 storm to impact Americans since Trump blew into the Oval Office – Irma, 8 months into his presidency, Puerto Rico devastating Maria and Michael last October. Between landfalls of Irma and Maria, Trump said he “never even knew” they (Category 5) existed. The man is a category 5 disaster .

Do we give up? Scream? Hope he isn’t re-elected?  Here’s an idea – what if we put him in a wind tunnel with a golf club and bucket of balls? Never mind, he’d simper “fake” wind velocity, blame Hillary, Mexicans, eagle killing wind energy, climate change clowns and left wing media fear mongering. How about this, we reclassify meteorological cauldrons in terms Trump understands, no more F scale tornados, category 1-5 hurricanes. Lets lump all natural disasters together, rate them on the Golf Scale.

Oh man, see Trump smile. Thumbs up, now he understands.

 

Northern Hemisphere Aurora Alert


As I write, streams of solar wind advance at 594.5 Km/second. Commanded by CH58+, a impressive coronal hole poised to deliver rare auroral punctuation as far south as Washington State, Idaho, Montana, Michigan and Minnesota.

Auroras happen when electrons energized by acceleration collide with Earth’s upper atmosphere. Acceleration allows energized electrons to follow Earth’s magnetic field downward to the poles. Anywhere from 80 – 500 Km above Earth’s surface, electrons collide with oxygen & nitrogen atoms, spiking the atoms’ energy. Soon after, atoms relax to their former energy state – relaxation creates light known as aurora borealis. Initially light forms an arc from horizon to horizon, within a few hours arcs twist and sway in upper atmosphere wind.

A geomagnetic storm warning issued by NOAA, Space Weather Prediction Center, forecasts G1 (minor) activity August 31, increasing to G2 (moderate) September 1st as solar wind blows Earthward at 650 Km/second.

Its been years since space weather issued public alert of aurora over Greater Vancouver. Auroras are fickle, space weather makes no promises. That said, if you find yourself away from city lights with clear skies, don’t miss an opportunity for Aurora to wrap her arms around you. Once you meet Aurora, night skies become a source of wonder.

Geomagnetic Storm Aurora Alert


Tonight into tomorrow, northern hemisphere sky watchers as far south as Iowa or Michigan to Washington State are on aurora alert. Auroras are caused by charged particles hitching a ride on solar wind, dark skies turn undulating curtains of mischievous colour when charged particles interact with molecules in our atmosphere. Usually, our magnetosphere acts as a planetary shield preventing geomagnetic interaction of charged particles. Every so often fast moving particles overwhelm our magnetic field, create an opening and light up night skies.

On May 12, a magnetic filament on the sun, seen here, became unstable and erupted. (NASA/SDO)

Since Monday, 3 additional solar eruptions sent fast moving charged particles our way. As a result the auroral oval (doughnut shaped ring around the pole where charged particles follow magnetic field lines, reason why far northern latitudes regularly witness geomagnetic storms), has shifted far to the south.

The colour of that light depends on the kind of molecule and the altitude of the collision.

Green is the most common colour, produced when the particles collide with oxygen at an altitude of around 100 to 300 km. At about 300 to 400 km, the interaction with oxygen produces red. Pink occurs below 100 km when nitrogen atoms are struck.

This link – https://www.cbc.ca/news2/interactives/solar-flares/index.html is worth a ponder. One of the best I’ve found in terms of understanding what makes space weather tick.

Bottom line – Space Weather Prediction Centre forecasters say there’s a 75% chance of geomagnetic storm activity tonight. If your skies are clear, go outside. If she’s willing, Aurora will find you. Opportunities like this don’t come along every day.

 

Chemically Enhanced Aurora


On April 5 NASA scientists launched sounding rocket mission AZURE (Auroral Zone Upwelling Rocket Experiment) from Norway’s Andoya Space Center. Twin rockets deployed chemical tracers capable of allowing researchers to track the flow of neutral and charged particles during an active geomagnetic storm. Emergency service switchboards were inundated with UFO sighting hysteria – seems no one bothered to alert residents of AZURE’s chemical meddling.

Lights over Lapland  webcam operator Chad Blakely captured the first chemical puffs. Video below from Adrien Mauduit documents the spectacle.

 

Twilight


This evening, gloriously bruised skies created a twilight ponder. Twilight struck with realization most of us take her mesmerizing palette for granted. Far from a cosmic constant, twilight requires atmosphere to scatter rays of light in advance and conclusion of a visible Sun above the horizon.

Civil twilight falls when the sun is 6 degrees below the horizon. In the morning this is known as dawn, in the evening, dusk. This is the limit at which twilight illumination is sufficient, under good weather conditions, for terrestrial objects to be clearly distinguished; at the beginning of morning civil twilight, or end of evening civil twilight, the horizon is clearly defined and the brightest stars are visible under good atmospheric conditions in the absence of moonlight or other illumination. In the morning before the beginning of civil twilight and in the evening after the end of civil twilight, artificial illumination is normally required to carry on ordinary outdoor activities.


Nautical twilight begins when the Sun is 12 degrees below the horizon. At the beginning or end of nautical twilight, under good atmospheric conditions and in the absence of other illumination, general outlines of ground objects may be distinguishable, but detailed outdoor operations are not possible, and the horizon is indistinct.


Astronomical twilight defines a Sun 18 degrees below the horizon. Before the beginning of astronomical twilight in the morning and after the end of astronomical twilight in the evening the Sun does not contribute to sky illumination; for a considerable interval after the beginning of morning twilight and before the end of evening twilight, sky illumination is so faint that it is practically imperceptible.

Civil, nautical, astronomical, three clearly defined twilights that forgot to mention – twilight is also a colour, emotion and source of cosmic wonder unique to our planet.

 

Geomagnetic Bliss By Adrien Mauduit


From Adrien Mauduit at the Aurora observatory, Senja Island, Norway on March 17, 2019…

“It all started at around 10:00pm LT. Almost nothing until then when all of a sudden a big band appeared in the south. Around 10:30pm LT, a very nice show happened with some colorful and fast moving coronas.”

Adrien Mauduit is a visionary, an artist who captures the essence of Aurora in mesmerizing detail. Join me in appreciation of his vision by clicking on the link below and following Adrien Mauduit.

Magnetic Vibrations


To the delight of Aurora watchers Earth’s magnetic field vibrates in protest of unrelenting solar wind. An Earth facing hole of monstrous proportion opened on the Sun, belching winds of 600 Km/second (that’s almost 1.2 mph ) toward our planet. Defensive vibrating twists in Earth’s magnetic field ignited powerful geomagnetic storms.

Astronomers predict intense aurora activity to continue for several days.

The current auroral oval commands the Northern Hemisphere. Anyone living under the oval owes it to themselves to look up under clear dark skies. Those lucky enough to meet  Aurora, embrace her stamp of indelible wonder. She’s waiting – all you have to do is find her.
