A gigantic gap has appeared near the Sun’s equator and it is emitting powerful streams of radiation towards the Earth. Scientists say this is out of the ordinary. Here’s why A giant hole has emerged in the atmosphere of the Sun and it has resulted in a solar storm. Image courtesy: NOAASatellites/X The Sun and its many mysteries continue.
It was 20 times larger than the Earth and was discovered near the Sun’s south pole. The gaping hole reportedly unleashed solar winds of 2.9 million kmph towards Earth. It resulted in the most powerful geomagnetic storm to hit Earth in more than six years. The Sun's explosive peak, solar maximum, could begin in early 2024. Reuters
An enormous dark hole has opened up in the sun's surface and is spewing powerful streams of unusually fast radiation, known as solar wind, right at Earth. The size and orientation of the temporary gap, which is wider than 60 Earths, is unprecedented at this stage of the solar cycle, scientists say.
Since Dec. 4, the solar void has been pointing directly at Earth. Coronal holes occur when the magnetic fields that hold the sun in place suddenly open up, causing the contents of the sun's upper surface to stream away in the form of solar wind, according to the National Oceanic and Atmospheric Administration (NOAA).
The gap in the Sun is a coronal hole. These develop at any time on the Sun but are more common during the years around the solar minimum, the beginning of a solar cycle.
And on Nov. 28, an "almost X-class" solar flare shot out of the sun and birthed a cannibal CME that hit Earth and triggered a geomagnetic storm, which lit up lower latitudes with auroras over the weekend. The recent surge in solar activity is likely a sign that we are right on the cusp of solar maximum.

Coronal holes can develop at any time and location on the Sun, but are more common and persistent during the years around solar minimum. The more persistent coronal holes can sometimes last through several solar rotations (27-day periods).
SWPC forecasters use their synoptic maps to view the various characteristics of solar surface at a locked-in time, on a daily basis. They create a snapshot of the features of the Sun each day by drawing the various phenomena they see, including active regions, coronal holes, neutral lines (boundary between magnetic polarities), plages and ...

Coronal holes occur when the Sun''s magnetic field is open to interplanetary space. Conversely, in regions where the solar magnetic fields loop back to the Sun forming arches, x-ray and UV images show bright areas. The brightest points in the images are generally at the top of the magnetic loops or arches.
Ground-mounted solar panels are a popular alternative to rooftop solar. They often cost more to install but can also produce more energy over time. Updated 3 days ago Ground-mounted solar panels: what you need to know Written by Zeeshan Hyder Find out what solar panels cost in your area Ground-mounted solar panels are a great alternative for customers who want solar – but …
Whether installed on the roof or on the ground, solar panels can save the average UK home £537 a year on their energy bills. If your property consumes a lot of energy and can fit more solar panels on the ground than on the roof, then ground-mounted solar panels might be the better option for you.
Materials Used in Solar Steel Panel Mounting Structures. There are several materials used in mounting structures for solar products, including the following: Cold-Formed Steel (CFS): This material has high strength, a long lifespan, and affordability. It is frequently used for solar panel systems that are roof-mounted and ground-mounted.
Ground-mount solar arrays are usually installed in rows that are oriented to face south (in the northern hemisphere) to capture the maximum amount of sunlight. The layout—whether in a portrait or landscape orientation—can impact how much space is needed. A landscape layout, where the longer side of the panel is horizontal, can often require slightly …
A coronal hole at the Sun''s north pole observed in soft X-ray. Coronal hole size and population correspond with the solar cycle. As the Sun heads toward solar maximum, the coronal holes move closer and closer to the Sun''s poles.

The solar corona is the outer atmosphere of the Sun, extending from the solar "surface" out into space. It is a region which is difficult to observe, being seen only during solar eclipses or with special equipment. A coronal hole is a large region in the corona which is less dense and is cooler than its surrounds. Such holes may appear at any ...
Solar minimum refers to a period of several Earth years when the TSI is lowest; solar maximum refers the years when TSI is highest. During solar maximum, activity on the Sun and the effects of space weather on our terrestrial environment are high.

Coronal hole size and population correspond with the solar cycle. As the Sun heads toward solar maximum, the coronal holes move closer and closer to the Sun''s poles. During solar maxima, the number of coronal holes decreases until the magnetic fields on the Sun reverse. Afterwards, new coronal holes appear near the new poles. The coronal holes then increase in size and number, exte…

Now astronomers are alarmed by a massive coronal hole that has formed recently on the solar surface. The gigantic gap, which is wider than 60 Earths, is temporary. It has appeared near the Sun''s equator and is spewing powerful streams of unusually fast radiation, known as solar winds, towards our planet, reports Live Science .
Within a few solar radii of the Sun''s visible surface, magnetic forces are thought to be the cause of the structuring seen at the times of total solar eclipse, such as helmet streamers and coronal holes. Coronal holes are now known to be regions where the density of the corona is considerably reduced, causing a relatively dark region to appear ...

Solar radiation contains a considerable amount of ultraviolet radiation, of which especially the short wavelength part below 315 nm is considered to be harmful to life on earth. The range between 280 and 315 nm is designated as UV-B radiation. The stratospheric ozone layer acts as a very efficient natural filter for UV-B radiation. It is in fact the most important …
Ground mounted solar panels and roof solar panels both harness sunlight for energy but have different advantages. Ground mounted panels can be placed and angled for maximum sun exposure, are easier to clean and maintain, but can take up considerable space. Roof solar panels are more commonly used due to space efficiency and they have minimal …
