Solar (Stormy) Weather

Solar weather forecasting vital as sun gears up for wild ride

Nascent science crucial for satellites, communications, power grids and other tech at risk


Following an extended quiet period, the sun is ramping up for an era of intense activity, and researchers are prepping to prevent solar storms from disrupting life here on Earth.

For the first time, scientists say, it's possible to predict how solar storms will hit our planet, much like meteorologists predict how hurricanes will hit a coastline. This early warning allows power grids to adjust for electrical fluctuations, and airlines to switch to alternative communication systems that won't be affected by the vagaries of space weather.

Yet this forecasting ability is in its nascent stage, experts say, and still leaves a lot of gaps to fill when it comes to space weather.

I'm crossing my fingers the "curse" part doesn't apply.

I actually check SpaceWeather.com sometimes before I yell at one the satellite broadcasters for crappy service.

More may be on the way ...
Massive solar storm 'could knock out radio signals' over next three days, warn scientists

"The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center wrote: ‘Category G1 (Minor) geomagnetic storms are expected 28 and 29 December due to multiple coronal mass ejection arrivals. R1 (Minor) radio blackouts are expected until 31 December.’
.....
A coronal mass ejection contains billions of tons of gases bursting with X-rays and ultraviolet radiation that are flung into space at around 5million mph.
They are mind-bogglingly hot – around 100,000,000C.
The Earth is occasionally hosed by these ejections, leading to amazing shimmering light shows.
They are caused by the ionised solar particles becoming imprisoned by Earth’s magnetic field, exciting the gases in the atmosphere and emitting bursts of energy in the form of light.
However, these particles can also cause magnetic storms, which in extreme cases have been known to disrupt satellites and electricity grids.
In 1989, a CME was held responsible for leaving six million people in Quebec, Canada, without power.
Last month one of the largest storms our star can produce was detected.
Known as an X1.9 flare, it was one of the biggest seen in years. "

If you get a good aurora take some pics. It's overcast here and normally too far south anyway.

Thanks for the link.

We should be OK here in the Colorado mountains...as far as I know, solar flares don't disrupt candles, lanterns and cooking fires!

Another blast coming our way, EXCERPT;

Word of today's blast, technically known as a coronal mass ejection or CME, comes via SpaceWeather.com's Tony Phillips. NASA says the outburst sparked an M3.2-class solar flare, as well as a stream of electrically charged particles that is due to interact with Earth's magnetic field on Saturday. "Viewers can be on the lookout for increased aurora," NASA says.
M-class flares are capable of causing brief radio blackouts near the poles as well as minor radiation storms, but it's unlikely that this one will disrupt communication or power transmission networks. The forecast would be different if it were an X-class storm heading our way. As the sun approaches the peak of its 11-year activity cycle in 2013 or so, we can expect to see more powerful solar outbursts.

So far, no interruptions of any kind here in our area.

Kind of like Y2K.

Me too.

No internet outages or mobile phone outages.

Have any measures been taken to protect the electrical grid o other infrastructure?
