A massive sun observed in the sun is turning towards the Earth and is expected to increase in size in the coming days.
The area, dubbed AR2770, has a ‘dark primary core’ the width of Mars and a number of ‘crater-sized’ spots that cast over its surface.
The Sun is a member of the Solar Cycle 25, the new 11-year period of electromagnetic activity, and was observed to be struck by small flares.
Although the AR2770 still has to produce a ‘killer’ solar flare, experts are holding a tight watch in an effort to prepare for such an event that could knock with electrical operations and facilities on our planet.

A massive sun observed in the sun is turning towards the Earth and is expected to increase in size in the coming days. The area, called AR2770, has a ‘dark primary core’ the width of Mars and a number of ‘crater-sized’ spotlets that line its surface.
The new point of the sun was spotted by amateur astronomer Martin Wise, who grabbed the image from Trenton, Florida.
“This sun was an easy target for my solar telescope,” Urti said, noting that he used an 8-inch stretch with secure solar filters to capture the photo.
The AR2770 is said to have emitted a number of Class B flames, the lowest class of solar flares, which have sent small ionization waves through the Earth’s atmosphere, Space Weather reports.
However, the point is growing and increased activity is possible in the coming days that may produce more intense solar flares.
The new point of the sun was spotted by amateur astronomer Martin Wise, who grabbed the image from Trenton, Florida. According to NASA, ‘solar flares are a sudden burst of energy caused by the interruption, intersection or rearrangement of magnetic field lines near sunspots’
According to NASA, ‘solar flares are a sudden burst of energy caused by interference, intersection or rearrangement of magnetic field lines near sunspots.’
Predicting when solar activity will increase could potentially protect astronauts in orbit, as well as prevent the destruction of technologies such as satellites.
In June, scientists with the University of Warwick discovered a new sundial that could better calculate the time of sunrise and sunset.
Lead author Professor Sandra Chapman said: ‘Big events can happen at any time, but they are much more likely around the solar maximum. By clearly listing the observations, we find that in 150 years of geomagnetic activity on earth, only a few percent occur during these quiet conditions. ‘
‘The ability to assess the risk of an impending solar superstorm occurring is essential for space and terrestrial technologies which are particularly sensitive to space weather, such as satellites, communications systems, power distribution, and aviation.
“If you have a space-sensitive system in space, you need to know how likely a major event is, and it is useful to know when we are in a quiet period, as it allows maintenance and other activities that make the systems temporarily more fragile. “
The team used solar observations over the past 200 years and mapped solar activity over 18 solar cycles into a standardized 11-year cycle – the sun begins a new solar cycle sometimes 11 years.

In the middle of the cycle, solar activity increases which produces more flare and radiation – all of which can be measured from sunspots.
The team used the daily record of the number of solar available since 1818 to compile solar activity, allowing them to see the correct lighting and turn off solar activity times.
Once the clock is built from sun observations, it can be used to order observations of solar activity and space weather.
‘Scientists spend their lives trying to read the book of nature. ‘Sometimes we create a new way of transforming data and what seemed messy and complicated is suddenly pretty simple,’ Chapman said.
“In this case, our sundial method clearly showed ‘on’ and ‘off’ times by demarcating quiet and active intervals for space weather for the first time.”
STORMS SOLAR INTRODUCTION A SECOND DANGER TO ASTRONAUTS AND CAN HAVE SATELLITES
Solar storm, or solar activity, can be divided into four main ingredients that could have impacts on Earth:
- Solar flashes: A major explosion in the sun’s atmosphere. These flashes are made by photons traveling directly from the flash point. Solar flares affect the Earth only when they occur on the sun side opposite the Earth.
- Coronary mass extraction (CME): Large clouds of plasma and magnetic field erupting from the sun. These clouds can erupt in any direction, and then continue in that direction, plowing through the solar wind. These clouds only cause impacts on the Earth when they target the Earth.
- High speed solar wind currents: These come from coral holes in the sun, which form everywhere in the sun and usually only when they are closer to the solar equator do winds affect the Earth.
- Solar energy particles: High-energy charged particles thought to be emitted mainly by shocks formed in the front of coronary mass extractions and solar flares. When a CME cloud plows through the solar wind, solar energy particles can be produced and because they are charged, they follow the magnetic field lines between the Sun and the Earth. Only charged particles following the magnetic field lines that intersect the Earth will have an impact.
While these may seem dangerous, astronauts are not in immediate danger of these phenomena due to the relatively low orbit of guided missions.
However, they should be concerned about cumulative exposure during space walks.
This photo shows the sun’s coral holes in an x-ray image. The sun’s outer atmosphere, the corona, is structured by strong magnetic fields, which when closed can cause the atmosphere to suddenly and violently release bubbles or tongues of gas and magnetic fields called coronal masses.
Damage caused by solar storms
Solar flares can damage satellites and have a huge financial cost.
Charged particles can also threaten overhead lines by disturbing the Earth’s magnetic field.
Too large igniters can even create currents within the power grid and knock power supplies.
When Mass Coronal Ejections hit the Earth they cause geomagnetic storms and extended auroras.
They can disrupt radio waves, GPS coordinates and overload electrical systems.
A large power flux can leak into high voltage networks and permanently damage transformers.
This could close businesses and homes around the world.
