NOAA issues space weather G3 warning: "Strong to extreme"
VOA/ NASA ^ | October 1 | VOA/NASA

Posted on 09/30/2012 10:59:48 PM PDT by PghBaldy

Space Weather Message Code: ALTK06 Serial Number: 294 Issue Time: 2012 Oct 01 0443 UTC

ALERT: Geomagnetic K-index of 6 Threshold Reached: 2012 Oct 01 0439 UTC Synoptic Period: 0300-0600 UTC Active Warning: Yes NOAA Scale: G2 - Moderate Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude. Induced Currents - Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms. Spacecraft - Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible. Radio - HF (high frequency) radio propagation can fade at higher latitudes. Aurora - Aurora may be seen as low as New York to Wisconsin to Washington state.


TOPICS: News/Current Events
KEYWORDS: aurora; nasa; noaa; spaceweather
Maybe someone more knowledgeable can explain the significance of this. Can be bad news for electronics, satellites and people in space right now?

The fact the aurora might be seen as far south as PA (in one of the earlier alerts) is interesting.

Sounds like high solar activity.
Solar winds reacting with our ionosphere and magnetic fields.

That mucks up stuff like radio that exploits natural phenomena.
Temporarily.

Don’t these educated idiots know how to say something in plain English? If it weren’t for the reference to auroras, I would have no idea what they were blabbering about.

THe first rule of writing is that you put your subject of discussion in the first sentence.

I guess they failed English 101.

I’ve seen a red and a green aurora in Arlington,VA and a white one in Baltimore, Md. Diffuse structure but COOL!

Not a big deal, but it could make for some pretty lights.
The Aurora.

Amen.

I haven’t seen the aroura for ages but have seen it as low as Ohio green red and blue

We used to see them all the time in Kevlavic. We were there during a solar minimum. I can only imagine what they look like with this solar activity.

This is an alert intended for those who depend on radio communication systems. It isn’t intended for general consumption.

For those of us who use HF comm systems, it’s written in terse, but perfectly understandable language. The lead-in tells me everything I need to know:

“ALERT: Geomagnetic K-index of 6”

For those who know about geomagnetic activity and the effects on radio communication, that’s all that really needs to be said. For you to have seen an aurora in the VA/MD area, the K-index was probably 8 or 9.

For those folks who just want a prediction of where an aurora might be visible, there’s a different web site:

http://www.swpc.noaa.gov/pmap/pmapN.html

As for effects on the vast majority of people and their lives: Little to none. If the magnetic field of the earth is hammered quickly with a big flux, then induced ground currents can cause instability or failures in the power grid(s), especially in northern regions (eg, Hydro Quebec).

One of the best sites for graphical predictions of where you *might* see an aurora based on the Kp index is out of the University of Alaska at Fairbanks:

One of my Buds, a photographer, had a chance to go to Fairbanks and shoot the Aurora.

It was -50 below and he had the camera buried in his clothes to keep it warm.

He got exactly one green shot of it before the shutter mechanism froze up LoL

He was kinda bummed

I’ve been in temps down to -47F. Winter ceases to be funny below -20F.

One of the things that might have caused your buddy’s camera to freeze up is the condensing moisture on the camera from his body. I’ve found that keeping gear like guns, cameras, etc inside my clothes leads to failures from moisture that condenses on the object (which will be cooler than my body in those temps), and then taking those objects out of my coat means that they freeze up instantly.

I’ve found it to be better to put the item in a dry environment before going outside, and not letting it get moistened by my body when I’m outside. It might be a real bother to deal with cameras, radio equipment and other stuff that’s wicked cold and you need to take off your gloves to operate the fine little buttons and knobs, but the alternative is worse.

Here’s a nice set of images of photos sent in from all over the world. Many of them have multiple photos once you click on a photo.

Too many lights in Seattle!

Seems more like it will create severe attenuation of signals temporarily but that’s about it.

DOUBLE IMPACT: Earth’s magnetic field is reverberating in response to a pair of impacts on Sept. 30th. A weak interplanetary shock wave hit Earth at 10:25 UT followed by a stronger CME strike at approximately 22:30 UT. Observers in Norway are reporting significant ground currents, while the Arctic Circle is glowing with Northern Lights. High-latitude sky watchers should be alert for auroras, especially during the hours around local midnight.

I was trying to do a little JT65 work this morning on 40 and 20 and it was pointless. (JT65 is a mode of digital communications, especially suited of low signal strength)

Don’t these educated idiots know how to say something in plain English?

Doesn't all this solar activity ALSO indicate additional infrared (or thermal) radiation? As in warming of the atmosphere and oceans?

Maybe they worded it this way in order to shield the delicate and sacred "anthropogenic global warming" narrative.

Hopefully so...I could stand a nice mild winter.

Anyone?

Winter ceases to be funny below -20F

Once the snow starts squeeching like busted styrofoam underfoot, you know it's cold.

Anything warm with only a little moisture on it should sublimate the moisture in short order... If there is a lot, fuhgeddaboutit.

Most lubricants, even light oils, will gel or stiffen badly (a few synthetics won't). A friend's SKS wouldn't cycle (until I cleaned the gunk off the gas piston). The lubricant/preservative in there was solid.

Thanks all for your comments. Is it significant that this warning came with supposedly no warning, late on a Sunday night?

To people who make a habit of watching the sun for disturbances, they knew something was coming.

See, the sun rotates on a 27 day interval. So if you see a big CME or flare on October 1, you should expect to see something 27 days later. The change in the K index was larger 28 days ago than now...
