The sunspot may herald an impending solar storm that could reach
Earth in one to three days, according to researchers at the National Oceanic
and Atmospheric Administration (NOAA). If so, it could disrupt GPS signals,
radio transmissions, and power grids.
What is a sunspot?
Sunspots are actually storms that appear on our star. They
are larger and darker than normal areas and appear as dark spots that can span
up to 100,000 miles. Most of these blemishes fade in 11 days, but some
have lasted for weeks. And unlike solar flares—flashes that shoot out from
intense magnetic activity—sunspots typically don’t have much effect on humans
here on Earth.
What could happen if there is an explosion
An explosion in our atmosphere would release massive amounts
of charged particles into space. This solar weather can interfere with GPS, satellite communications, and power grids. A severe geomagnetic storm
can cause widespread power outages—and even blackouts lasting for days. If that
wasn’t enough, it could trigger failure in transformers that maintain electric
transmission systems, including grids supplying homes and businesses with
electricity.
How often do they occur?
Sunspots are transient phenomena that appear and disappear for hours to days. They tend to follow cycles
averaging 11 years in length. The number of sunspots visible at any time is
not directly related to their intensity. Some large spots can develop and decay
within days, while smaller spots can persist for weeks or months.
The number of sunspots visible on the surface at any one time is not directly
related to their intensity—many small spots can be more intense than larger
ones.
Do we have to worry about it right now?
Thankfully, no. There’s not going to be a big solar flare
for at least three days, if then. However, we should keep our eyes out because
it could start to grow rapidly and catch us by surprise. For now, we can all
rest easy—even though there’s still plenty of fun in space.
Is this bad for us here on Earth?
Suppose a giant solar flare erupts, sending our way charged particles at 1-2 million miles per hour (the speed at which those particles travel depends on what kind of storm it is). In that case, these can cause problems for
satellites, radio and television signals, and even electrical grids. But more
often than not, storms are non-events. Likely, you won’t even know
about them unless you study space weather closely.
How can you watch the effects of the spot with your own eyes?
You don’t need fancy equipment to see what’s happening in
our solar system. According to scientists, you can use two different
approaches to watch our stars: either at night or during the day. During the nighttime, when you look at the sky, spot Orion and other constellations with
your naked eye.
