The magnetic field of the Earth acts as an obstacle to the magnetized flowing plasma from the Sun, called the solar wind (which I believe was high last week).
The Magnetic field forms a cavity in the shape of a blunt body with its nose at this position and an extended tail. The cavity flares on either side of the Earth and the solar wind stretches the terrestrial magnetic field in the antisolar direction.
Since the solar wind is traveling relative to the Earth at speeds greater than the speed of compressional waves that are needed to divert the solar wind around the Earth's magnetosphere, a bow shock is formed which slows the flow and diverts it around the Earth.
Am I close teacher? Please edit if I am wrong - this is what I've learned, but I am not a scientist.
Mod edit: Adding source.

What does the atmosphere protect us from again?
The magnetic feild is related, I suggest you look closer instead of flaming, if you cant put an arguement up without referring to star treck, I suggest you merely find something that proves me wrong, why not a stereo report?
I also got hold of a photo showing that it was the largest sun spot recorded.
The news report from the Gympie times is correct....
the Examiner is always a waste of time, so dont you dare refer to my information ever coming from that again, I NEVER USE THAT WEBSITE.
If you dare put words in my mouth again I will rip your arguements to shreads.

“Active region 1024 is putting on a fantastic show.
The center of this region is incredibly bright and fluctuating.”
- Pete Lawrence, Amateur Astronomer, Selsey, U.K.
Spaceweather.com reports, “Sunspot 1024 has crackled with B- and C-class solar flares. Solar observers haven't seen an active region like this one in more than two years. It is big, complex, and rapidly growing. The magnetic polarity of the sunspot, revealed by SOHO magnetograms, show that it is a member of new Solar Cycle 24.”

well, the lightning storms were pretty interesting here in northern philippines. thanks guys. at least i knew why thor was upset.
worst that happened was the power out due to lightning. lasted for a few minutes. but it was arguably an excited lightning storm - witnessed and noticed by a few locals.
other than that, nada to report/?
