Solar Sunspots, Flares, and Prominences are related. The sunspot is a temporary phenomenon on the surface of the Sun, and are believed to be a low temperature region extending outwards from the surface of the Sun. Their temperature is at least 1000 degrees cooler than that of the sun's surface, thus they show as relatively dark spots. But only compared to the sun - their temperature is still 3 to 4 thousand degrees.
These eruptions are believed to be caused by magnetic lines of force pulling plasma from the surface. Naturally, at four to six thousand degrees, there are no magnetic materials on the sun, the magnetic fields are caused by plasma (electrical) currents flowing near the surface, thus inducing the magnetic field.
[No moving electrons = no magnetic field.]
The solar wind is a more or less steady flow of charged particles from the sun. The charged particles ejected by the magnetic fields, will add to the solar wind in a more turbulent fashion.
On Earth we experience these as massive flows of charged particles, and when they interact with the upper atmosphere gives us the polar auroras. They can cause damage to electrical and telephone systems, satellites, and even to aircraft. Earth's magnetic field funnels these charged particles to the polar regions, and in a severe solar storm, aircraft will avoid polar routes otherwise the passengers and crew could be subject to damaging ionizing radiation.
You should never look at the sun directly. The projection of the image of a pinhole in a sheet of cardboard, on to a sheet of white paper, will give you a good surface on which to make a record. The camera obscura of old.
You may use the camera obscura to record the forthcoming Transit of Venus across the sun's disc. Draw a circle on the paper, which matches the apparent size of the sun's disc. This will aid you in keeping the image steady.
(But of course, the image will move across your paper during the Transit - you'll have to move your paper. )

What causes magnetic storms?
Magnetic storms, also known as geomagnetic storms, are caused by disturbances in the Earth's magnetosphere, primarily triggered by solar activity. When the Sun releases large bursts of solar wind and coronal mass ejections (CMEs), these charged particles interact with the Earth's magnetic field. This interaction can lead to fluctuations in the magnetic field and increased ionospheric currents, resulting in magnetic storms. These storms can disrupt satellite operations, communication systems, and power grids on Earth.
How does a solar storm and solar flare affect earth?
Magnetic Storms have a severe affect on our technological and electrical infrastructure, both in space and on the ground. Usually Earth's magnetic field, generated by the dynamo under earth's lithosphere, protects us from magnetic disturbances, but severe magnetic storms have in the past knocked out power grids in the entire province of Quebec. Magnetic Storms would have a severe effect, and would likely, en masse, shut down large amounts of current human grids and technological infrastructure, as concluded by the National Academy of Sciences.
What is a Geomagnetic storms?
Geomagnetic storms are disturbances in the Earth's magnetosphere caused by solar wind interacting with the Earth's magnetic field. These storms can result in enhanced auroras, disruptions to satellite and radio communications, and potential damage to power grids. They are often brought on by solar flares or coronal mass ejections from the sun.
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.
What huge magnetic storms may be responsible for variations in temperatures and precipitation?
Huge magnetic storms, such as solar flares and coronal mass ejections (CMEs) from the Sun, can influence Earth's magnetosphere and atmosphere. These events can disrupt global weather patterns by altering the ionosphere and affecting atmospheric circulation. As a result, they may lead to variations in temperatures and precipitation, particularly in regions sensitive to solar activity. Additionally, changes in the Earth's magnetic field during such storms can impact climate systems, potentially leading to extreme weather events.
What are sudden disturbances in earth's magnetic field called?
Sudden disturbances in the Earth's magnetic field are called magnetic storms. These storms are typically caused by solar wind interacting with Earth's magnetosphere, resulting in fluctuations and disturbances in the magnetic field. Magnetic storms can affect a variety of technologies such as power grids, satellites, and communication systems.

What is created by the suns magnetic field?
The sun's magnetic field creates phenomena such as solar flares, coronal mass ejections, and the solar wind. The interaction of these phenomena with Earth's magnetic field can lead to geomagnetic storms and auroras.
How can solar storms affect the Earth?
Solar storms can disrupt satellites, power grids, and radio communications on Earth by interfering with their electronics and signals. They can also create beautiful auroras in the atmosphere and pose health risks to astronauts in space due to increased radiation levels. Additionally, solar storms can affect Earth's magnetic field, causing compasses to be temporarily inaccurate.
Does a geo storm have 2 solenoids?
A geo storm, typically referring to a geomagnetic storm caused by solar activity, does not have solenoids in the traditional sense. However, in the context of Earth’s magnetic field, solenoids can be used to model magnetic fields or to study the effects of geomagnetic storms in experimental setups. The storms themselves are more related to interactions between solar wind and Earth’s magnetosphere rather than any physical solenoids.
Magnetic storms are a result of an increase in solar wind caused by eruptions on the sun called?
solar flares or coronal mass ejections (CMEs). These eruptions release a large amount of charged particles into space, leading to disturbances in Earth's magnetosphere when they interact with our planet's magnetic field. This can result in geomagnetic storms that can affect communication systems and power grids on Earth.
What happens when solar wind hits the earth?
When solar wind hits the Earth's magnetosphere, it can cause disturbances in the magnetic field and lead to geomagnetic storms. These storms can result in beautiful auroras at the poles but may also disrupt satellites, communication systems, and power grids on Earth. Additionally, the solar wind can strip away the outer layers of a planet's atmosphere if it lacks a strong magnetic field to protect it, like what happened to Mars.
An effect of solar storms that can be viewed with the naked eye?
The northern lights have been seen by human beings for thousands of years. They are caused when solar storms eject large bursts of solar wind into the Earth's magnetic field. Radiation, including ultraviolet radiation, is also produced by solar storms. But ultraviolet radiation cannot be seen by the naked eye. Thunder and lightning are not caused by solar storms.

What are storms that occur on the surface of the sun?
Storms on the surface of the sun, known as solar storms, primarily include solar flares and coronal mass ejections (CMEs). Solar flares are intense bursts of radiation caused by the release of magnetic energy, while CMEs involve the ejection of large quantities of plasma and magnetic field from the sun's corona. These storms can impact space weather, affecting satellite operations, communication systems, and even power grids on Earth. They are driven by the sun's magnetic activity and cycles, particularly during solar maximum periods.
How are solar storms connected to the moon?
Solar storms can affect the space environment around the moon, leading to increased radiation levels and potential disruption of communication signals. The moon has no magnetic field to shield it from solar winds and energetic particles, making it more vulnerable to the effects of solar storms.
What evidence do you see in the sky when the solar magnetic storms break through your magnetic shield?
