The Sun’s magnetic field reverses polarity right around the peak of the solar cycle. So, the upcoming reversal will mark the peak of Solar Cycle 24.
That’s not to say that powerful solar flares won’t occur after the peak just that half of ‘solar max’ is still to come.
Solar physicist Phil Scherrer, at Stanford explains the reversal:
“The sun’s polar magnetic fields weaken, go to zero and then emerge again with the opposite polarity. This is a regular part of the solar
During the reversal, cosmic rays made up of high-energy particles accelerated to almost light speed by supernova explosions. Such cosmic rays pose
significant dangers to astronauts and to space probes. So, what negative effects should the ISS experience, if any?
It’s also thought that they may have some impact on the Earth’s climate and cloud formation. The current sheet acts as a barrier to cosmic rays,
deflecting them as they attempt to penetrate the inner solar system. A wavy, crinkly sheet acts as a better shield against these energetic particles
from deep space.
Solar physicist Todd Hoeksema, of Stanford University says that a complete field reversal is happening.
“This change will have ripple effects throughout the solar system.”
I know this is the fourth flip. Will this pole exchange be any different than the previous reversed polarities?
Will Comet ISON, and it’s combustion upon meeting with the Sun’s magnetic waves, create a solar flair class X?
Solar flares are classified as A, B, C, M or X according to the peak flux (in watts per square metre, W/m2) of 100 to 800 picometre X-rays near Earth,
as measured on the GOES spacecraft.
Classification Peak Flux Range at 100-800 picometre
A < 10−7
B 10−7 – 10−6
C 10−6 – 10−5
M 10−5 – 10−4
X > 10−4
What’s interesting about all of this is that X class are the biggest ones! The biggest X class that has ever been recorded is X28
The last time this happened was about 10,000 years ago at the end of the last ice age. DHS is currently prepping for something major with most
preparations needed to be complete by October. Could they also know of a big event that is about to take place & effect the entire world
