Please don't apologize, XKrossX - You've managed to put in words things that I feel I've been unable to say, but I've come to the same conclusion that you have.

Thank you.

I agree with you whole heartedly.

I'd tell you all about how I feel I was affected, but it's all just too personal for me to write about here. VERY similar to your descriptions.

I'm going to be focused on celebrating CANADA day today!

How often do you see the aurora around Sudbury, tribewilder? I think the different colors are due to the ionization of certain chemicals in different parts of the atmosphere.. The color gives a hint to the chemical composition @ 50km I think? Someone correct that one if I'm wrong..



Sorry, I was just going back over this thread and must not have seen this before.

As a child, during the 60's and 70's, my parents owned a house that had a huge picture window that faced north. There were also very few houses in the area and as such, there were very few "light distractions".

From what I recall, at least 2-3 times a year, we would witness the Northern Lights. There was never a warning on the news or anything, they just showed up, and we watched them. Sometimes my Dad would even wake my up to witness the spectacle. They always appeared in the fall or winter if I recall correctly.

The last time I saw them was around 7 years ago. The girl I was seeing at the time had a 13 year old son and he literally freaked when he saw them and I spent more time trying to calm him down than actually watching the show. The whole Northern hemisphere was lit up (green), and the curtains were plentiful.

The only reason I don't see them anymore is I don't have any view of the north from my place. I'm sure there have been plenty that I missed.

I watched a show with Valerie Pringle about a place that caters to people wanting to witness the Northern Lights and most of the people that show up are from Japan.

I don't have a link to the show but I do have a link to the place.

Here is a link to the Aurora webcam..Aurora Webcam

And finally, here is the link to the Aurora Skystation..Aurora Skystation

I don't know of the cost or anything but if you have never seen them, this looks like the best place to go..

Again sorry for not answering sooner, I just didn't see the question.

Phage or anyone who can answer for that matter...

When the solar particles hit the magnestosphere and redirect to the pole prodiucing the aurora borealis. Is this a constant thing that happens or only when the sunspots appear and then release the solar flare....

the reason I ask is the Id love to see the aurora one day and want to know if I need to be aware of any flares or will I see it no matter what time of year I go....

Actually, the charged particles aren't really hitting the Earth, they are hitting the magnetosphere very far from the Earth. The magnetosphere then redirects the particles to the poles where they can interact with the upper atmosphere (higher than 50km) and produce aurora.

The speed and temperature of the solar wind made a jump a few days ago as a result of a hole in the Sun's corona which was aimed in our direction around the 20th of the month. There were also a couple of sunspots which appeared on the 22nd. This would also contribute to maintaining the increase. Both speed and temperature have been declining since they peaked but the effects of another coronal hole on the 24th could the the cause of the jump you noticed today.
www.swpc.noaa.gov...

The peak on the 25th was not particularly impressive, reaching speeds of only about 500 km/s. A really good blast from a coronal hole can get as high 800 km/s. A CME (coronal mass ejection) can produce velocities of over 1,500 km/s. This was just a little burp. But there is not much agreement on the relationship between the velocity of the solar wind and geomagnetic storms which are caused by interactions of various factors within the solar wind and the Earth's magnetic field. It takes more than a fast solar wind to produce a magnetic storm.
www.spacew.com...

So while we are our way toward the next maximum, what we are seeing right now is really no big deal. The current cycle is predicted to peak in may of 2013 and is predicted to have less activity than average. But as yet there is no way to predict the intensity of that activity. It could be relatively quiet or it could be bad.
