A
very large sunspot is currently being tracked by NASA scientists.
It has unleashed three large solar flares on September 7th, 8th, and
9th. The flare on September 7th was catagorized as an X-17, the
fifth largest recorded by NASA. The flare on the 8th was a X-5
and the flare on the 9th was a X-1.
Brief radio
blackouts has been the only effects they have had on the Earth.
Scientists predict that, as they approach Earth, there will be even
more disruptions over the next two weeks. The affected areas will
be in spacecraft operations, electrical power systems, high-frequency
communications, and low-frequency navigational systems.
This is the same
sunspot that erupted in the middle of August. This sunspot caused
strong auroras as far south as Utah and Colorado. Over the past
two weeks, the active area has caused eruptions acorss the surface of
the sun as it made its way to the far side of the sun. This will
cause auroras to start and show in mostly the northern regions of the
Earth.
The solar flares
and coronal mass ejections (CME) are the most powerful in the solar
system and can pack the force of one billion megatons of nuclear
warheads. These CMEs are normally associated as giant clouds of
plasma in space. They are caused by the buildup and sudden
release of magnetic stress on the solar surface over the magnetic poles
of the sun.
