Solar flares - coronal mass ejections

There have been two large solar flares in the last few days.
Today's was the bigger of the two, and its effects are due to arrive at 2.57am Thursday morning.

Event Issue Date: 2011-02-15 05:47:44.0 GMT
CME Arrival Time: 2011-02-17 02:57:50.0 GMT
Arrival Time Confidence Level: ± 6 hours
Disturbance Duration: 6 hours
Disturbance Duration Confidence Level: ± 8 hours
Magnetopause Standoff Distance: 5.5 Re
Thu, 17 Feb 2011 02:57:50 GMT



Tuesday's solar flare disrupted some radio communications.

Today's bigger flare is likely to do the same somewhere in the world, and can disrupt satellites and power supplies, so -

'Coronal Mass Ejections'

Hells Bells!

I though this was summat to do with what came out the morning after a bad vindaloo curry.

It isn't in the mainstream news yet
Sun unleashes powerful 'Valentine's Day Solar Flare' (video)
Scientists are predicting even more X-class flares, including Chamberlain. “This is the first of probably many more X-class flare to occur over the next 2 to 4 years as we reach the peak and then descend back down from solar cycle 24 maximum.”
Theoretical physicist and professor, Michio Kaku, appeared on Fox News in 2009 and warned about the “temper tantrum” of our sun. Kaku stated that the sun can release a “tsunami of radiation” that can take out communications satellites, GPS systems, weather satellites and many others.




We may get see the Aurora Borealis further south than normal.

So the sunspots will peak in 2012-2014 on a 24 year cycle. That means they have been increasing since 2000. Any connection with the gradual climate change and 'Global Warming'?
Of course not, that's all our fault and will cost us a lot of money and make a relatively few people very rich!

yup the biggest con job ever pulled off next to religon under one word "green"

back when the last severe climate change happened cars and anti persperant were to blame then as well ,infact its well documented that dinosours were killed off because boy racers choked the planet with fumes from their cars ;)

As the solar cycle gets nearer its maximum, there is a greater chance of us seeing the Northern Lights here in Lancs.

If you want to see them, you can ask to be advised by email from Lancaster UNI when the chances to see are likely.

Welcome to AuroraWatch

I was all excited, until a scientist was interviewed on the BBC breakfast news, and said it's now unlikely we'll see the lights in the UK tonight, even in the Scottish highlands.

If you look at this site
SpaceWeather.com -- News and information about meteor showers, solar flares, auroras, and near-Earth asteroids
you can see that northern england was in the auroral field of view.
We could have seen mild changes in the sky colour if it hadn't been so very cloudy.

Re: Solar flares - coronal mass ejections
 
I am sure that most people think that the light show lasts all night but with my experience it doesn’t. You may get a minute or so at a time. Whilst I was in the middle of Iceland I stopped up most of the night waiting to see the lights, and waited, and waited. Eventually they started, I called the others who where asleep in a hut. By the time they where out of the windowless hut the show had ended.

We did get one more glance ( same trip ) whilst we where in the most northern curry house in the world, in Reykjavik. We saw the common green and the more rare red/purple. It lasted seconds.

This was probably at a low sun spot activity season.

Remember it well. Hydro Quebec is particularly vulnerable. Much of the power comes from the north, in Baie James. Quebec is a major exporter of electricity.

seems they must have been a common occurance at one time , no idea how often they happen these days , hence the song

Around midnight last night there was an X class solar flare.
If you watched the Horizon documentary on BBC2 last night you will be aware of the implications of increased sun activity due this year.

Since we are talking about Astronomy and uncommon occurances like the Northern Lights, I wondered how many of you had ever properly seen the rest of our Galaxy which passes over our heads every night but is obscured by light pollution.

Re: Solar flares - coronal mass ejections
 
This event might be more than just the aurora borealis visible further south than usual.

Radio ham sites today are warning of radio and satellite disruption when the CME arrives tomorrow (a 'glancing blow' to the ionosphere),

...and disruption of the upper atmosphere is strongly suspected to contribute towards earthquakes, volcanic eruptions and severe weather events
Can Solar Activity Cause Earthquakes, Volcanoes and Extreme Weather? → Washingtons Blog
"On a significant number of occasions, satellites have picked up disturbances in this part of the atmosphere 100-600km above areas that have later been hit by earthquakes.

One of the most important of these is a fluctuation in the density of electrons and other electrically-charged particles in the ionosphere.

One study looked at over 100 earthquakes with magnitudes of 5.0 or larger in Taiwan over several decades. The researchers found that almost all of the earthquakes down to a depth of about 35km were preceded by distinct electrical disturbances in the ionosphere. "

Well, Mags, I'd better get my last minute reply in before I'm cut off from you and the rest of the internet!

Don't worry about it, if it happens, it happens, nowt we can do about it.

Try the pics in this...
Northern Lights: Extraordinary display in the skies above YORKSHIRE | Mail Online

I wouldn't have said the aurora was uncommon, it's just that it only occurs at certain times of the year and is easier to see and more spectacular when certain solar and magnetic conditions coincide. Travel agents are certainly making a killing out of it at the moment.

What amused me was after we came back from a visit to the North Cape of Norway last summer, so many people asked us if we had seen the northern lights, despite the skies up there never going dark 24/7 thanks to the midnight sun!!

No Mags never think of you as worried , just a worrier.

Was supposed to be a good chance it could be seen over East Lancashire on Thursday night.

Sat on patio step (camera in hand) for ages, until it clouded over. No sighting.

Just finished up with a cold ... :(

Even if they're up there, with our weather, we'd better stick to the Illuminations, if we want to see guaranteed Northern Lights.

In the early hours of Thursday the sun emitted an M class flare, which supplies us, here in NWest England, with the potential to see some northern lights.
