Shocking! Sunspot grows 10 times its size! Giant G5 class solar storm coming for Earth?

A new sunspot, AR3085, has been spotted by scientists. Worryingly, this sunspot has grown ten times its size in just two days. Will this spell a disaster for Earth with a G5 class solar storm? Find out.

WARNING! Solar Storm to hit Earth soon

1/5 According to Spaceweather.com’s report, the new sunspot is so huge that it is even changing the way the sun vibrates. The Space Weather Prediction Center, National Oceanic and Atmospheric Administration (NOAA) predicted that the geomagnetic field around Earth would be unsettled over the weekend which could disrupt the radio-magnetic sphere.

2/5 Spaceweather.com said, “A high speed stream of solar wind is approaching Earth. Estimated time of arrival: Aug. 9th. The gaseous material is flowing from an equatorial hole in the sun's atmosphere. High-latitude sky watchers should be alert for auroras.” (SDO/NASA)

3/5 Solar storms occur due to a coronal mass ejection (CME) that is set off on the surface of the Sun. As per the K-index, which measures the magnetic field around the Earth, solar storms are divided into 5 classes from G-1 to G-5. The G-1 is the lowest impact solar G5 is given to the most severe solar storms. (Pixabay)

4/5 According to NASA, Sunspots are dark areas on the solar surface which contain strong magnetic fields that are constantly shifting and can form and dissipate over periods of days or weeks. They occur when strong magnetic fields emerge through the solar surface and allow the area to cool slightly. (Pixabay)

5/5 When solar flares hit Earth, they interact with the Earth’s electromagnetic field to cause a Geomagnetic storm. It may cause blackouts, GPS problems. However, if the solar storm is big enough, it can wreak havoc on all the earth's technological infrastructure. It is also the reason behind the stunning night-sky phenomenon that we know as Auroras or Northern Lights. (Pixabay)

It seems that the Sun is regaining its violent demeanor after a week of low activity. Even as the Sun is moving towards the peak of its solar cycle, the solar activity was surprisingly low the previous week. Even the sunspot which was capable of producing M-class solar flares disappeared without an explosion. But all that is about to change. A new sunspot has appeared on the Sun which has worried the scientists. This sunspot grew ten times its original size in just two days. Worse still, it has now joined up with another sunspot to become a double sunspot group. Each of the cores of these sunspots are as wide as the Earth. The scariest part of this development is that the sunspots are directly facing the Earth and and if they explode they will send a horrifically destructive solar storm hurtling towards the Earth.

First noted by SpaceWeather.com, the website reported that, “Two days ago sunspot AR3085 barely existed. Since then it has grown more than 10-fold, turning itself into a double sunspot group with cores nearly as wide as Earth. Watch this movie. The active region is directly facing Earth and crackling with C-class solar flares”. SpaceWeather has also shared an image of the sunspot that you can check here.

Solar storm scare after massive double sunspot grows tenfold

Just last month, a similar sunspot called AR3068 grew triple its size and caused a massive G3 class solar storm on Earth which resulted in GPS disruption and radio blackouts in multiple regions on Earth. Fast moving solar winds from the flare that went off on the Sun even created a temporary co-rotating interaction region (CIR) in Earth's magnetosphere, opening a crack and letting in more solar radiation than normal and increasing the intensity of the solar storm.

While it is too early to predict whether a similar or even more intense solar storm will strike the Earth, it is possible. Scientists are monitoring this particularly unstable sunspot because of its instability. It may cause power outages and satellite damage if it blasts a G5 solar storm like the Carrington event. It can also damage electronic gadgets and disrupt power grids. Worse still, it can also cause forest fires due to its highly charged radiation.
