A dark sunspot that faces directly to the Earth has doubled in size in just 24 hours and is likely to send middle-class eruptions in the near future.
Tony Phillips, author of SpaceWeather.com, wrote on Wednesday: “Yesterday the sunspot AR3038 was big. Today it is huge.
And now it is said to measure three times the size of the Earth.
Not only does the sunspot AR30398 look directly at our planet, but it also has an unstable beta-gamma magnetic field that contains enough energy to cause a short interruption of the radio.

Sunspots are dark areas of the sun where it is cooler than other parts of the surface. Solar eruptions occur near these dark areas of the star.
Solar eruptions and coronal mass ejections come from these regions, and when they explode toward Earth, they can cause geomagnetic storms that produce beautiful glow, as well as endanger energy networks and satellites.
AR3038 is undoubtedly a big sunspot – a beachgoer in New Jersey spotted it in the sun as it rose over the Atlantic Ocean.
A pair of massive swarms of sunspots, some large enough to engulf the entire Earth, appeared on the surface of the sun in April.

Named AR2993 and AR2994, the two active regions sent scientists in exaggeration to see if the Earth needed to prepare for powerful solar flares – but fortunately neither was sent in our way.
However, in early April, the Earth slightly missed a plasma ejection associated with a group of sunspots that appeared earlier on the star.
The recent increase in solar activity is the result of its approach to the most active phase in its 11-year solar cycle – reaching peak activity in 2024.
Studies show that the level of solar activity that is currently occurring is approximately the same as 11 years ago, at the same time as the last cycle.
“I’m sure we’ll see bigger active regions in the next few years,” said NASA solar physicist Dean Pesnell, speaking to Live Science.
“The active regions 2993 and 2994 are medium in size and do not represent the best that Solar Cycle 25 can produce.”
Jan Jansens of the Solar Center for Excellence in Brussels told Live Science that the many solar flares and coronal mass ejections are “typical at this stage of the solar cycle”, with some targeting the Earth but missing.

“As the solar cycle reaches its maximum, more and more complex areas of sunspots become visible, which can then produce solar flares.”
Solar eruptions have letter classes, with A-Class being the weakest, followed by B, C and M-Class, with X-Class being the strongest of the categories. Then they are given size – small numbers represent smaller eruptions in the class.
The X1 eruption is ten times less powerful than the most intense solar eruption possible, and the most powerful recorded since 2003 overloads sensors like the X28.
The National Oceanic and Atmospheric Administration’s (NOAA) Space Forecasting Center found that Sunday’s eruption caused eclipses of certain radio frequencies below 30 MHz in Southeast Asia and Australia.
Despite the eruption, which causes a radio eclipse, the plasma from the eruption will not hit the Earth.
“Coronal eruptions and discharges will become more frequent over the next few years, increasing the level of danger from solar activity,” Pesnell told Live Science.
There has been no extreme CME or solar eruption in the modern world – the last being the Carrington event of 1859 – creating a geomagnetic storm of radiance that is occurring worldwide, as well as fires at telegraph stations.
