Large Solar Flare To Glance Off Earth

samzenpus posted more than 2 years ago | from the raise-shields dept.

Space 154

JoeRobe writes "According to spaceweather.com, a major X5 solar flare is on its way to deliver a glancing blow to the Earth's magnetic field. This is the second x-class flare to be released by the same sunspot in the past few days, the first being an X1. In both cases, the sunspot (spot 1429) was not directly facing Earth, but it is still active, and poses a threat for a large, Earth-directed flare in the next few days."

It's been corrected; meaning the main story. The first sentence originally read, "According to spaceweather.com, a major X5 solar flare is on it's way to deliver a glancing blow to the Earth's magnetic field." That is incorrect. Dropping the apostrophe has now made it correct.

Anonymous Coward | more than 2 years ago | (#39281111)

In one of the short stories in Niven's "Draco Tavern", most stars are populated by plasma beings that learn over time how to manage the "weather" in their home. In this story, a single survivor of a magnetic "plague" is being held in quarantine before immigrating to our star. The concern is that the refugee might give the plague to the denizens of our own star- When this happened to the immigrant's home, their infrastructure deteriorated to the point where they couldn't manage the weather anymore and their sun went nova. I always wished he had taken that short story and run with it for awhile.

maybe i am just being pedantic...but for the gp yes...the solar flare could affect the asteroid's orbit...however it will probably only be on the order of millimeters over the next thousand years.

as well as the flashlight would affect the cannonballs trajectory...however likely not enough to be measurable before it hit something.

Note that it's not just more light that will hit the asteroid, but also a sparse cloud of ions with measurable mass. But still, the effect will not be sustained enough to cause a major disturbance, or even be distinguishable from measurement noise.

That's true, which is why I said "mid-latitude and high-latitude" in my original post. I'm aware of the possibility that MSesow lives in an equatorial region, but in case he/she lives in a mid- or high-latitude region, these charts may be useful.

too late -- the flare already hit. (5, Informative)

oneiros27 (46144) | more than 2 years ago | (#39279583)

The flare travels at the speed of light ... so we've already been hit by it. The CME [wikipedia.org] is what's going to come tomorrow morning (or tonight, depending on your time zone)

And the "spot number" as this article called it is actually NOAA Active Region #11429. I'm sick of this modulo 10000 value -- AR1429 was decades ago. (the list I'm looking at starts at AR6777, which was in August 1991)

I'll leave it for some other time to rant about the difference between 'sunspot number' (a subjective number to describe the amount of spot coverage on the sun in the visible spectrum which goes back centuries) vs. 'active region number' (a NOAA index of spots seen in x-ray)

Re:too late -- the flare already hit. (1)

JoeRobe (207552) | more than 2 years ago | (#39280035)

You're totally right, my bad. I should have said the CME from the flare will deliver a glancing blow to the planet. I didn't know that bit about the AR1429 vs. AR11429, very interesting. Is that something that NOAA has started doing, or is it just spaceweather.com? (I didn't call it "spot number", I just called it "spot 1429". Should have said "AR11429".)

Why does it seem I am the only one that is concerned about what's going to happen when one of these flares whacks the power grid in the Northeast U.S.? http://en.wikipedia.org/wiki/Solar_storm_of_1859 [wikipedia.org] Oh, that's right - the US Gov't is real concerned too. - http://science.nasa.gov/science-news/science-at-nasa/2009/21jan_severespaceweather/ [nasa.gov] So here's what really concerns me - say, the entire Northeast grid goes down. There are a number of nuclear plants that have cooling pools for spent fuel rods, just like Fukushima. So what happens when - just like Fukushima - the power goes down and the pool pumps can't run for lack of electricity - Won't that be like Fukushima x (no. of nuclear plants in the Northeast)? Don't mean to be alarmist, but someone tell me where I am wrong on this?

Re:Carrington Event ? (3, Informative)

networkBoy (774728) | more than 2 years ago | (#39280219)

Because in the case of grid failure they will run on diesel generators.
Which are off and relatively safe until the grid blows, which is after the CME is passed, then they start (even if a delay of manual starting is required, no worries). And in this case there is not a wall of seawater to drown the gennes.

Re:Carrington Event ? (1)

In order for it to be an issue, you will need a tidal wave to damage/remove the back up generators.

So, to answer your question, nothing. On the plus side, they will allows to start restoring electricity very quickly.

Re:Carrington Event ? (0)

Anonymous Coward | more than 2 years ago | (#39280305)

Ice cores contain thin nitrate-rich layers that can be used to reconstruct a history of past events before reliable observations. These show evidence that events of this magnitude—as measured by high-energy proton radiation, not geomagnetic effect—occur approximately once per 500 years, with events at least one-fifth as large occurring several times per century.[9] Less severe storms have occurred in 1921 and 1960, when widespread radio disruption was reported.

Re:Carrington Event ? (1)

JoeRobe (207552) | more than 2 years ago | (#39280991)

The Northeast grid has gone down [wikipedia.org] before, and there were no meltdowns. As other folks have pointed out, those things have backup generators. I assume that in the blackout of 2003, those generators kicked on.
