Enormous Sunspot, Raises Concerns , After Rapidly Doubling in Size.
'Newsweek' reports that a massive, earth-facing sunspot has doubled in size over 24 hours and has raised
concerns about a potential earth-bound solar flare.
Sunspots form over areas of the sun
where strong magnetic fields exist. .
These tangled magnetic fields can suddenly
reorganize themselves, releasing an explosion
of light and radiation in the form of a solar flare.
On June 20, NASA's Solar Dynamics
Observatory revealed how the sunspot
had significantly grown over the course of a day.
'Newsweek' reports that the massive sunspot has the potential to send an M-class solar flare at Earth.
As of June 21, the National Oceanic
and Atmospheric Administration's Space Weather
Prediction Center had not yet issued a solar flare warning.
Solar flares can interfere with
radio communications networks
and navigation systems on Earth.
M-class flares are actually quite common
and tend to cause moderate, short-lasting
radio blackout events.
X-class flares are the strongest type of solar flare and only occur about once every 11 years.
An X20 flare would be capable of causing
a total high-frequency radio blackout for several
hours on the sun-facing side of Earth.
