Most Powerful Geomagnetic Storm of Solar Cycle 24 Is Happening
astroengine writes: The most powerful solar storm of the current solar cycle is currently reverberating around the globe. Initially triggered by the impact of a coronal mass ejection (CME) hitting our planet's magnetosphere, a relatively mild geomagnetic storm erupted at around 04:30 UT (12:30 a.m. EDT), but it has since ramped-up to an impressive G4-class geomagnetic storm, priming high latitudes for some bright auroral displays.
Although to be fair, I stand in awe of the fact that the earth herself hadn't done more to cull the human population explosion.

It's time to shield your RAM or hope you got EEC.
Nah, nothing bad will ha(%^%^$##*

Shields up, take warp drive offline, give maneuvering thrusters and brace for impact!
obviously he wasn't using ECC and the flare had corrupted 2 bits.
Or maybe he *was* using ECC. ECC can only correct 1 bit.
I can't believe this story was accepted when the one directly below it in the link was about how you could purchase "Space Yeast" that was in space during this storm. And you get a package of control, regular yeast too! I wonder if the loaf of bread made from it will be stretchy, invisible, turn into rock, or catch on fire?
You insensitive clod!
Seriously, the clouds have moved in right on cue...

Well, you don't necessarily need to use something to contain the ejection if you're using coronacidal cream properly, but the cream doesn't protect you from coronally-transmitted diseases.

'coronal mass ejection' is now my new favorite innuendo.

I can see them from Mid-Western Saskatchewan. Brilliant green flowing across the skyline. We watched them from the edge of the city for about an hour tonight. You could see them even in the city with street lights on. Then they just disappeared very abruptly
wrong. a simple parity check can only correct one bit, most ECC memory is quite capable of multi bit flip correction through interleaving especially with neighbouring bits.
Parity can not correct any bits. It only detects single bit errors. While many ECC codes exist, the Hamming code overwhelmingly used in computer memories can correct one bit in a 64-bit word and detect two bit errors.

By the way, this storm is already almost over. It's real peak was early Tuesday morning when the Bz hit 8.33. I snapped almost 500 pics during the early morning hours.
Here's the album for anyone who's interested.

Actually, memory effects generally come from proton radiation storms, not geomagnetic storms.
Radiation storms are usually associated with large flares. There need not be an Earth-directed CME, but it does help if a recent event created a stronger magnetic path to Earth. If that was a stream, by the time it gets towards Earth, the end that it's originating from on the sun is near or even beyond the western (rotating away) edge. So most events that cause radiation storms are "near the western limb". (see Parker Spiral)
Most of the time the atmosphere stops any particles, but when the energy is high there can be secondary collisions. An event much more rare, but usually associated with a radiation storm, is a GLE (ground level enhancement). A spike in high energy radiation level can do strange things. Creating an invisible trail, if a particle goes in the right spot, it can cause some smoke detectors to chirp out of the blue. (Usually just once, less often a few times, not at the lower volume or regular interval of a low-battery warning). Since the radiation bursts are seldom and brief, they don't add up to much exposure on Earth.
Those with counters may see a slight increase in background on the leading edge CME and fast solar wind. And since fast events clear away some slower but heavier particles that would collide with the atmosphere, there's often a drop to below normal background after an event passes. When CMEs are more frequent, like this last week, an earlier CME sweeping away some solar wind particles leaves a path when a subsequent fast CME won't get slowed down as much as usual. And if there is a fast stream from a coronal hole nearby, we we also have now), it may be sped up and spread out less. There was also a filament eruption. Those usually spread less than flare CMEs, and tend to be denser. I'm not sure what happened with the filament eruption on the 11th. I think it went west-north-west.
For many people, radon from soil and well water is far more likely to be of concern. Avoid taking long showers during a drought. More ground water is used during droughts, and that's what usually has the most radon.
Once again the power grid shrugs off this magnetic storm with a yawn.
But as soon as this storm has passed, a fresh set of scare stories will begin.

That's a great reply. Makes me glad that my water supply is from the Gulf of Saint Lawrence (well, except for what may have been dumped in it upstream and not removed by the filtration plant).

Auroras have been observed at latitudes as low as 48.000 N - see this article from the french News France 3
