Solar Flares

A solar flare is a sudden eruption of energy near the sun's surface. It causes a burst of brightening over sections of the surface.

231 Questions

What do solar flares release?

Solar flares release a burst of energy in the form of electromagnetic radiation, including X-rays and ultraviolet light. They can also release streams of charged particles into space called solar energetic particles.

How fast do solar flares travel?

Solar flares can travel away from the Sun at speeds ranging from 1,000 to 2,000 kilometers per second (about 600 to 1,200 miles per second). These high speeds are due to the energy released during the flare, which can accelerate particles to such velocities.

Do solar flares cause global warming?

Solar flares do not cause global warming. Global warming is primarily driven by human activities, such as burning fossil fuels and deforestation, which increase the concentration of greenhouse gases in the atmosphere. Solar flares are intense bursts of radiation from the sun that can affect radio communications and satellite technology, but they do not play a significant role in Earth's climate change.

Solar flares last for many years?

Solar flares are intense bursts of radiation from the sun that typically last from a few minutes to a few hours. While the effects of a solar flare, like geomagnetic storms, can persist for days to weeks, the actual flare itself does not last for many years.

How do solar flares create Auroras?

The radiation emitted from solar flares skiffs across the ozone layer of the earth, at both the north and south poles, creating the phenomenon commonly know as the "Northern" and "Southern" Lights respectively.

Do the solar flares emit CMEs?

Yes, solar flares can emit coronal mass ejections (CMEs) as they release a burst of energy and magnetic field into space. CMEs are massive eruptions of magnetized plasma from the Sun's corona that can affect space weather and produce geomagnetic storms when they interact with the Earth's magnetic field.

What are effects of solar flares?

solar flares can wipe out global communication. they can temporarily disable satellites and that can wipeout telephones, internet, and x-box live. the charged particles coming off the sun and going with the solar winds can come into the earth's atmosphere. that can cause Auroras. charged particles coming in and mixing with high-altitude air molecules that cause the Auroras.

Will there be an abundance of solar flares in 2012?

We really have no idea how active the Sun will be during 2012. Because this is the period of increasing activity (we're currently about 1.5 years into the 11-year sunspot cycle) we can expect that there will be more flares in 2012 than we'll have in 2011, and probably quite a few more than we had in 2010. But whether 2012 will be anywhere close to a record would be impossible to say at this point.

However, depending on the direction and severity of a solar flare, an Electromagnetic Pulse (EMP) can be generated, powerful enough to damage electrical equipment (cell phones, computers, cameras, etc.). I myself looked into forms of protection against these threats. Beyond just knowing the facts there are products out there to help.

Can solar flares affect earth's weather?

Yes. Solar Flares do affect earth.

As earth is protected by a very strong magnetic field, the effect is of no actual danger to life on earth.

For the planet it self, solar flares would not be of any danger at all even if life were exterminated by their magnitude.

Solar Flares do cause implications regarding electronics placed in orbits around the earth. They can during violent sun-storms cause saturation in electronics and burn circuitry. This particularly in satellite's.

For humans... The danger is only theoretical as in if sun-storms become so violent that they penetrate the magnetic field protecting our planet. This does not often happen and even if it happens, this would most likely only be marginally.

What is soler wind and soler flare?

Solar wind is a stream of charged particles released from the Sun's upper atmosphere. Solar flares are sudden bursts of high-energy radiation that occur on the Sun's surface, often accompanied by ejections of material into space. Both solar wind and solar flares can impact Earth's magnetic field and technology.

Why can solar flares be dangerous?

Solar flares can be dangerous because they release high-energy radiation (including X-rays and ultraviolet light) that can harm astronauts in space, disrupt satellite communications and navigation systems, and even affect power grids on Earth. They can also cause geomagnetic storms that lead to increased aurora activity and potential damage to electronic equipment.

Why do solar flares and prominences occur in 11 year cycles?

Solar flares and prominences occur in 11-year cycles because of the Sun's magnetic field. This is known as the solar cycle, which is caused by the changing magnetic properties of the Sun. The cycle is driven by the Sun's internal dynamo mechanism, with peaks and valleys in solar activity occurring roughly every 11 years.

Dose Mars has solar flares?

Mars does not have solar flares in the same way that Earth does. Solar flares are caused by activity on the Sun, and Mars lacks a strong magnetic field to shield it from such events. However, Mars can still be affected by solar activity in other ways, such as through changes in its atmosphere.

Can you have human ashes fired from a flare?

No, it is not safe or legal to fire human ashes from a flare. Flares are designed for signaling or lighting purposes, and using them for scattering ashes can be dangerous and disrespectful. It's best to follow proper protocols and regulations for scattering ashes in a safe and respectful manner.

When is the next solor flare?

Solar flares are difficult to predict accurately, but they tend to occur at the peak of the 11-year solar cycle. The current solar cycle, Solar Cycle 25, is expected to peak around 2025-2026, so there may be an increased likelihood of solar flares around that time. However, exact timing of solar flares is uncertain.

What does artistic flare mean?

Artistic flare refers to a person's unique and creative expression in their artwork. It often involves a distinctive style, original ideas, and a strong sense of creativity that sets their work apart from others.

What is flare of the ship?

The flare of a ship refers to the curvature or outward slope of a ship's hull towards the bow. It is designed to help deflect waves and provide a more stable ride in rough conditions. A greater flare can also contribute to a drier deck by minimizing spray.

What are the main forms of radiation in which solar flares release energy?

During their existence, solar flares release enormous amounts of energy across the entire electromagnetic spectrum. Much of it is in the form of ultraviolet radiation, radio waves, and X-ray emission.

More dangerous to human astronauts is the flow of energetic protons released by these eruptions, which can cause severe injury to living tissue.

Why do you think prominences are probably more exciting to see than sunspots or solar flares?

Prominences are large, bright, and dynamic structures that extend outwards from the Sun's surface, creating a visually stunning display. They are also long-lasting compared to sunspots or solar flares, making them a more captivating phenomenon to observe. Additionally, prominences can have a significant impact on space weather, which adds to their intrigue and importance in solar study.

How are sunspots related to prominence and solar flares?

The sun don't really need sunspots cause sunspots are related to several features on the sun's surface but prominences and solar flares need sunspots.
Sunspots are the places where the magnetic field lines of the Sun poke out of the Sun to form loops.

Where they poke out they are seens as prominences against the edge of the Sun's visible disk during an eclipse of the Sun.

The looped magnetic field lines contain energy and are unstable, When they break and reconnect they release this energy suddenly and cause solar flares.

What is a flare and blowdown system?

A blowdown system is a collection of controls, valves and pipes by which liquid or gas pressure contained within a process, piping, or pressure vessel, can be safely relieved.

In the event that the blowdown will release flammable or hazardous vapors to the atmosphere, the flammable or hazardous vapors may be routed to a flare for combustion and destruction.

A flare may be as simple as a open section of pipe with a manual pilot light, or as sophisticated as a collection of venturi drive burner tubes.

Solar flares cause magnetic what on earth?

Solar flares can cause disruptions in the Earth's magnetic field, leading to geomagnetic storms. These storms can affect technology and infrastructure by inducing currents in power grids and interfering with satellite communications.

Solar flares may be seen in the sun's what?

Solar flares, sunspots and prominences are features of the sun that have some effects on Earth: 1. Sunspots- Dark areas around the surface of the sun that are cooler than surrounding areas. They appear and disappear over a period of time. The period from minimum to maximum number of appearances of sunspots is the sunspot cycle, which occurs every 11 years. Sunspots are believed to have effects on Earth's weather and climate. Low temperatures in some countries and drought in other countries were observed during a period when very few sunspots appeared on the sun's surface. 2. Prominences- Arches of gas that rise from the sun's surface and flow back to it caused by magnetic fields of sunspots. Some prominences are in the forms of loops, curtains, or funnels. Solar prominences may last for many hours and can extend millions of kilometers above the surface of the sun. 3. Solar flares- Violent eruptions that are suddenly released and are caused by magnetic energy stored in the corona. Ultraviolet light and X rays from solar flares cause disruption of radio signals, making communication by radio and telephone difficult. Magnetic storms occur on Earth when electrically charged particles from the corona and solar flares ae added to the solar wind produced by the corona. When this happens, Earth's atmosphere radites beautiful lights called aurora borealis or northern lights. This same light is called the aurora australis in the southern hemisphere.

Why do solar flares occur?

Solar flares are bright, yet hard to observe in the light of sun.

Most certainly, what you wanted to know why do sunspotsappear black. This is because they are slighly colder than rest of the photosphere and by contrast look darker.
