Solar winds and geomagnetic solar storms
Minor G1 Geomagnetic
Storm Watch for 19 October
Most likely
aerea of Aurora Extent: the vicinity of the grren line (Kp 5)
NOAA
forecasters say there is a 60 % chance of G1 Class Geomagnetic storm on October
19th.
G1 conditions
are likely due to anticipated responses associated with the arrival of a
co-rotating interaction region (CIR) followed by a coronal hole high speed
stream
CIR’s are
transition zones between fast- and slow-moving solar wind streams.
Solar wind
plasma piles up in these regions, producing density gradients and shock waves
that do a good job of sparking auroras. The high speed stream is flowing from a
northern hole in the sun’s atmosphere shown here in extreme ultraviolet wavelength
from NASA’s Solar Dynamics Observatory. Arctic sky watchers should be alert for
auroras before the weekend.
What is
Space weather?
Space
weather refers to changes in the space environment …. Particularly the region between the earth and
sun. The ‘solar wind’ from the Sun
stream past the earth and is mostly deflected by the earth’s magnetic field,
but variations in the solar wind cause chances in the earth’s magnetic field.
Occasionally,
a huge release of magnetic energy, called solar flare, occurs in the sun.
Flares can produce large quantities of x-rays, which affect the earth’s
atmosphere. They can also accelerate atomic particles (mostly protons) to very
high speeds (a substantial fraction of the speed of light!)
These high
energy particles are dangerous. Most affects of space weather affect us to some
extend. Some aspects are benign but fascinating such as the aurora, and some
are malevolent.
The more
our society becomes dependent on technology and the more we utilise space, the
more we are affected by space weather.
(Note: in a vision, Jesus showed me a picture
of how he used his cupped hand to shove mass on the Sun's surface, creating a
sun hole from which solar winds are blown toward the earth, and these solar
winds can cause shape changes on Earth that the seismic activity and the volcanic
activity increase and that there are tsunamies, hurricanes, tornadoes, earth
fissures and cracks as well as all sorts of natural spectacles.The strength
determines and controls Jesus, because HE is the master of the natural forces
His Second Coming to Judgment, with Jesus' commitment to protect those who seek
Him and serve His will.)
