Approaching Solar Storm Forces ISS to Take Cover 118
vichyschwa writes "A Coronal Mass Ejection resulting from an X3 Solar Flare earlier today is forcing the ISS and Shuttle astronauts to take cover and may result in communication disruptions. Last week, the same sunspot generated what astronomers described as a rarely imaged solar tsunami. The activity began with an X9 flare Dec. 5. According to Spaceweather.com, "satellites may experience some glitches and reboots, but astronauts are in no danger." However, the astronauts were ordered to a protective area of the space station as a precaution."

From the Wikipedia article on Solar Flares: http://en.wikipedia.org/wiki/Solar_Flare [wikipedia.org]
Solar flares are classified as A, B, C, M or X according to the peak flux (in watts per square meter, W/m2) of 100 to 800 picometer [wikipedia.org] X-rays [wikipedia.org] near Earth, as measured on the GOES [wikipedia.org] spacecraft. Each class has a peak flux ten times greater than the preceding one, with X class flares having a peak flux of order 10-4 W/m2. Within a class there is a linear scale from 1 to 9, so an X2 flare is twice as powerful as an X1 flare, and is four times more powerful than an M5 flare. The more powerful M and X class flares are often associated with a variety of effects on the near-Earth space environment. Although the GOES classification is commonly used to indicate the size of a flare, it is only one measure.

Here is another reality regards these CME's and flares. The matter in them leaves the sun and accelerates rapidly upon exiting the sun. This isn't like the acceleration of a gun. In a gun once the bullet leaves the gun, it begins slowing down. In a CME the matter gets faster and faster on the way out like it was riding a railgun track all the way out. The matter in these X-Class flares left the sun and in about 16 hours are reaching the earth. They left the sun at a velocity that was a few thousand m

Bad math at work. By the scale listed, an M9 would be four times more powerful than an M5, so there is no way an X2 is four times more powerful than an M5. An X2 should be 7 times more powerful than an M5. (M6-M7-M8-M9-X-X1-X2)

It's friday, so I get into work early, before lunch even. The phone rings. Shit!
I turn the page on the excuse sheet. "SOLAR FLARES" stares out at me. I'd better read up on that. Two minutes later I'm ready to answer the phone.
"Hello?" I say.
"WHERE HAVE YOU BEEN, I'VE BEEN TRYING TO GET YOU ALL MORNING?!"
I hate it when they shout at me early in the morning. It always puts me in a bad mood. You know what I mean.
"Ah, yes. Well, there's been some solar activity this morning, it always disrupts electronics..." I say, sweet as a sugar pie.
"Huh? But I could get through to my friends?!"
"Yes, that's entirely possible, solar activity is very unpredictable in it's effects. Why last week, we had some files just dissappear from a guys account while he was working on it!"
"Really?"
"Straight Up! Hey, do you want me to check your account?"
"Yes please, I've got some important stuff in there!"

Word to the wise. I'm here to tell you that you only need to do this once to appreciate the benefit of a good barrel when fish shooting. I mean, unless you have some pretty large fish (especially in the head area), and a pretty small caliber weapon, you are at risk of not only offing the fish, but you are also liable to put an NRA certified water-draining hole in your barrel. Now me, I use fish-shooting barrels from the Ukraine, and I've never had an issue with water stained carpets.
Try explaining it to your significant other when they get home. "Have you been discharging weapons inside the apartment, again...?" - "Don't we recall what happened when you put the dartboard up on the wall at the end of the hall and shot at it with your new Glock? That little-bitty bullet went thru the dart board and the wall and all four of your alpaca sweaters hanging up on that end of the closet...right?"

I actually did this whilst at university, only against a door instead of a wall. The door in question was the front door, as this was the only corridor long enough to act as a range.
Although in the UK we only had air/CO2 powered pellet guns (albeit with 150m/s+ muzzle velocity, proper target pistols not BB guns), the stupidity of the situation did eventually dawn on us when the pizza guy rang the doorbell.

Had a friend at university who used to throw knives and had a target drawn on his door. He was chucking a knife at it when his room mate walked in a fraction of a second after he'd thrown it. So we're all sitting there in stunned silence as this door swings shut behind him with a knife positioned right behind his head and he looks at us all and says "What's the matter with you lot?"

You've been carrying around examples your entire life. Fluid-filled loops, one for each axis, little hairs along the inside to detect fluid rotation.
Try this. Sit up straight in a swivel chair, kick it into a spin, maintain the spin until you get used to it. Then quickly lean forward. You will then know exactly how a gyroscope feels when you try to tilt it. Have a bucket handy or do it on an empty stomach.
