Lately, I've been 'monitoring', if you will, the earths magnetic field, i've come across some strange looking activity periodically. I exchanged some emails with a guy from NASA today, Joseph Gurman, and he completely lost me with his answers and seemed to outright ignore some questions i asked. I'm no scientist or physicist, so it's useless for me to try to decipher most of the stuff he wrote to me.
Consider this magnetic field simulation. The latest images are from April 1st, 2012.
If you scroll down to the bottom of this page, and look at the very first image link At the very bottom of the list you will see that there is some strange activity going on with the magnetic field. It seems to fluctuate the further you go up the list. In late December, it was MUCH more dramatic. What, i wonder, could be causing this? Some have said solar activity, CMEs or what have you, but this doesn't make sense to me, solar activity was low during this time of the year apparently.
I've been reading that we are overdue for a pole reversal. I first noticed late December of 2011, the magnetic field of the planet was seemingly being repelled by something. The images were VERY dramatically different than the norm. I can not get these images from this time period easily,i will try. upon doing some googling, i found that there was a lot of seismic activity in late December, even the aurora borealis could be seen here in the states!
Basically, i would like someone to try to explain these weird anomalies in the magnetic field images, and possibly give an explanation to what could make something like this happen if these images are accurate. Also, i would love if someone could read the emails i got from Gurman and give me a 'for dummies' rundown. thanks in advance, oh scientific ones.
