APOD: Northern Lights over Prelude Lake (2010 Sep 17)

Image Northern Lights over Prelude Lake

Explanation: Curtains of shimmering green light sprawl across this gorgeous night skyscape. In the foreground lies the peaceful Prelude Lake, located about 30 kilometers east of Yellowknife, Northwest Territories, Canada. From high northern latitudes these mesmerizing northern lights, also known as the aurora borealis, are becoming a more familiar sight. As the September 23rd equinox approaches, nights grow longer and a favorable season for aurora begins. Recorded on September 11, this panoramic scene spans about 180 degrees. Brighter stars peering through the auroral glow at the left form the recognizable northern asterism, the Big Dipper. A more compact Pleiades star cluster shines at the far right.

<<Bartholomew and the Oobleck is a 1949 book by Dr. Seuss (Theodor Geisel). It follows the adventures of a young boy named Bartholomew, who must rescue his kingdom from a sticky substance called "oobleck". The book is a sequel of sorts to The 500 Hats of Bartholomew Cubbins. Unlike most of Geisel's books, which are written in anapestic tetrameter, Bartholomew and the Oobleck, like its predecessor, is a prose work.

In the book, the King of Didd announces that he is bored with sunshine, rain, fog, and snow, and tells his magicians to add some variety to the weather. As a result, large piles of sticky green oobleck fall throughout the kingdom, covering everything. The king soon regrets his wish, but since his magicians' cave has been buried in oobleck, he can do nothing to remove the substance. Eventually, his page, Bartholomew, advises him to say "I'm sorry." The king complies, and the oobleck melts away.

Geisel said he drew inspiration for the book from a conversation he overheard while stationed in Belgium during World War II. During a rainstorm, one of his fellow soldiers remarked, "Rain, always rain. Why can't we have something different for a change?"

The book opens with an explanation about how people in the Kingdom of Didd still talk about "The year the King got angry with the sky," and how Bartholomew Cubbins, King Derwin of Didd's page boy, saved the Kingdom. Throughout the year, Bartholomew sees the king getting angry at rain in spring, sun in summer, fog in autumn, and snow in winter. The king explains he's angry because he wants something new to come down from the sky, but when Bartholomew points out that "even kings can't rule the sky," the king vows to prove Bartholomew wrong.

One spring night, as he's getting ready for bed, the king gets the idea that ruling the sky is the task of his Royal Magicians so he orders Bartholomew to summon them. After expressing his wish to the magicians, they announce they can make something called Oobleck which won't look like the regular weather the king doesn't want. The magicians soon return to their secret cave on Mount Neeka Tave to make the oobleck.

After watching the cave all night, Bartholomew sees the first sign that the oobleck has been made and is falling the very next morning. When the king wakes up and sees the oobleck, Bartholomew tries to caution him on how big the falling oobleck is getting, but the king orders Bartholomew to tell the Royal Bell Ringer that today will be a holiday.

Bartholomew does as he's told, but when the bell ringer tries to ring the bell, it doesn't ring because oobleck has gotten into it. When Bartholomew and the bell ringer see a mother bird trapped in her nest by the oobleck, they see that it could be dangerous, so Bartholomew makes the decision to warn the kingdom.

First, Bartholomew warns the Royal Trumpeter about the oobleck, but when the trumpeter tries to sound the alarm, oobleck gets into the trumpet and the trumpeter gets his hand stuck trying to remove the oobleck. When Bartholomew tries to tell the Captain of the Guards to warn the kingdom, the captain instead, thinking the oobleck to be pretty, tries to prove to Bartholomew that he's not afraid by scooping some oobleck up with his sword and eating it, only to get his mouth stuck and breathe out green bubbles. Bartholomew tries to go to the Royal Stables for a horse to warn the kingdom himself, but even the stables are covered in oobleck.

As Bartholomew goes back inside, the falling blobs of oobleck, now as big as buckets full of brocolli, start to break into the palace, creating even more mess inside than outside. Bartholomew runs around warning everybody to stay undercover, but the palace servants and guards are soon stuck in the oobleck.

In the throne room, the king, now covered in oobleck himself, orders Bartholomew to summon the magicians to stop the storm, but when Bartholomew brings up the bad news that even the cave is covered in oobleck, the king gets the idea to use the magicians' magic words ("Shuffle Muffle Muzzle Duff") to stop the oobleck. Bartholomew finally gets the courage to tell the king off for making such a foolish wish and tells him to use simple words, like "I'm sorry," instead of magic words. At first, the king insists that he never says sorry, but once after Bartholomew states that he's no sort of king if he's covered in oobleck does the king finally admit his mistake and say "I'm sorry."

Straight after the king says those simple words, the Oobleck Storm breaks up and the sun melts away all the oobleck, freeing everybody in the process. At this point, the narrator states that maybe those simple words the king said were the magic words to stop the storm. After the oobleck is gone, Bartholomew takes the king to the bell tower and the king rings the bell proclaiming the day a holiday, dedicated not to oobleck, but to rain, sun, fog, and snow, the four things that have, and always should, come down from the sky.>>

PRELUDE
On the green sky, / a green star,/What to do, love,/¡ay! ... but lost?
The towers cast/with the cold fog,/How are they looking at us/with their windows?
Hundred green stars on a green sky,/do not see a hundred towers/white snow.
And this fear of mine/to make it alive/I decorate/with red smiles. Federico Garcia Lorca


PRELUDIO
Sobre el cielo verde, /un lucero verde,/¿qué ha de hacer, amor,/ ¡ay!... sino perderse?
Las torres fundidas/con la niebla fría, /¿cómo han de mirarnos /con sus ventanitas?
Cien luceros verdes /sobre un cielo verde, /no ven a cien torres /blancas, en la nieve.
Y esta angustia mía /para hacerla viva, /he de decorarla/con rojas sonrisas.

I think I may have been hit by oobleck… does it turn white on contact with humans?

I am wondering if that is Arcturus on the left side of the image just above the horizon under the 30 degree bent tree.

Parallelism in the earth's surface, Afghanistan, the blades of the helicopters, coated with titanium and nickel generate lighting effects when hitting the sand grains.

Léon, thank you for the Lorca! One of my favorites, and one who, along with Neruda, makes me wish I knew Spanish.

Hmm! APOD seems not to have any (many) photos of aurora australis taken from ground level. I wonder why.

Because it is strategically place over the ocean?

neufer, might you be able to explain something to me, please? I often look at http://www.spaceweather.com -- I do want very much to see an aurora someday! -- and though I've been looking at the site for some years, I still don't quite grasp the "Current Auroral Oval" image that appears in the left column. I assume the orange/yellow is where an aurora is likely to be; is that correct, do you know? What is the blue/purple part of the oval supposed to convey? (Besides ergs, I mean.) It often reaches down to cover all of Pennsylvania and even into Maryland, yet we are unlikely to see auroras here (even if the skies were dark).

I suppose my real question is: How do I read the "Current Auroral Oval" image?

As quickly as possible; stepping through this animation
will show you that Auroral activity varies dramatically in just minutes.

Here are NOAA's "Tips on Viewing the Aurora"

I personally haven't seen aurora in the United States since I was a child.
I'm sure that Chris or someone else here may have first hand knowledge on this matter.

Owlice, come to think of it, i also have not seen any Northern Lights since i was a kid. It would seem, like everything else, they are wearing out.
