Solar auroras are created by energetic particles colliding with atoms in upper atmosphere. These particles collide to create rainbow colours and radiate from lower altitudes. Auroras are caused by solar activity and are therefore usually associated with high levels of sun activity. Learn more about the science behind solar auroras and how they're caused. You may be surprised to discover that auroras can appear anywhere in the world.
Auroras are caused by energetic particles of the solar wind colliding with atoms of the upper atmosphere
The primary reason for the rise in brightness and movement is magnetic reconnection. NASA's THEMIS mission studies magnetic substorms. These storms are often accompanied with auroral lights. Five satellites and twenty ground stations are used to measure auroral light intensity and electrical currents in the earth's magnetic fields.
They radiate at lower altitudes
The majority of light emitted by the sun's solar aurora comes mainly from excited oxygen, which is the main component in the atmosphere at 100 km. These atoms are separated by the sun's ultraviolet radiation, which results in a curtain containing collective light that we call the aurora. Why are these curtains so faint? Let us explore this phenomenon to find out how they are made.
They can be any colour in the rainbow
A dazzling array is visible in the sky. The result of solar particles colliding with Earth's atmosphere 60 to 150 miles above the planet is an Aurora. It can be any color in the rainbow. Due to the high oxygen content, green is where you see the colours most clearly. The spectrum distribution of solar-aurora colours can change from a bright green, to a brilliant violet.
They are linked to high solar activity
As the sun approaches its 25th cycle, its dynamics will become more pronounced. This will result in a rise in solar flares and sunspots as well visible aurora. Scientists are currently developing forecasts for five to six years. The 2023 or 2026 solar maximum will be the next. To ensure that the aurora remain visible, scientists continue to monitor the sun's activities.
They can happen at anytime
Auroras on Earth are caused by the interaction between the solar wind and the magnetosphere. The solar wind's intensity and the effect it has on Earth’s upper atmosphere can vary. The type of aurora depends on the conditions. There are many possible physical scenarios that could lead to auroras. The solar wind is an energy source for auroras. However, it doesn't directly affect the upper air.
They can be seen over Io and Europa as well as Ganymede
Solar auroras are thought to depend on high-energy electrons. Previous dynamical simulations of Ganymede’s atmosphere didn't include critical electron kinetics nor consider the entire magnetosphere. To study Ganymede's magnetosphere, researchers now use the Gkeyll code from Princeton Plasma Physics Laboratory. The auroral strength of the emissions is affected when Jupiter's electrons collide with the polar region of the moons.
FAQ
Can I cancel my agreement at any time?
Yes. But you must do this within 14 calendar days of signing your contract. You can usually terminate your contract by giving written notice up to 7 working days before the end date specified in your contract. You may still owe money to the contractor if you fail to give sufficient notice.
What are the payment terms for the service/contractor I am required to pay?
The type of service provided will determine the payment schedule. A contractor might hire to install a roof. You would usually pay when the work is complete. However, when you purchase a product from a seller, such as a kitchen range oven, you may only pay once you have received and tested it.
What is a "service contract agreement"?
A Service Contract Agreement (SCA) is an agreement between two parties to provide services to each other. The SCA specifies the services to be provided, their cost, time and effort required, who will pay for them, and when they should start. It also stipulates what happens if either party breaches its obligations under the agreement.

How To
How to Write a Good Service Agreement
Remember that when you write a service agreement, you're trying to meet two requirements.
You must first satisfy the requirements set forth by the customer.
You must secondly comply with legal requirements.
It is important to ensure that you have the following items covered by your service agreement.
-
Identify the parties.
-
Define the subject matter.
-
Specify the duration of the agreement.
-
Determine whether you give any warranties.
-
Define the obligations and liabilities for both parties.
-
Establish the mode of payment.
-
Clarify how disputes will be settled.
-
Please provide details regarding any restrictions or special instructions.
-
Both parties must sign the contract.
-
Include a clause stating that the agreement has been read and understood before signing.
-
Make sure that you have a copy of the agreement with you.
-
Once you have completed the service agreement, review it carefully before you forward it to your buyer.
-
You can contact your supplier right away if you discover any issues with the agreement.
-
Send the revised version after everything has been fixed.
-
You should not sign an agreement until you receive confirmation from the buyer that they have accepted any changes.
-
Keep a copy and finalized copy of the original agreement.
-
In some countries, service providers are legally responsible for quality services to their customers.
-
In case of dispute, keep a record of all correspondence between yourselves and the customer.
-
Professional advice is always a good idea when you are drafting a service contract.
-
Be aware that the buyer could request an amendment to the contract terms after they have been accepted.
-
Always verify that you are comfortable with a change request before agreeing to it.
-
Never accept a change request without first checking.
-
Tell the customer why if you don't wish to accept the change.
-
If you are still not in agreement, then tell them that the change is unacceptable.
-
If the customer does not accept your decision, you can refuse to sign the contract.
-
Once the customer has accepted your decision, you can proceed with the contract.
-
You should agree to any changes to your contract terms.
-
Make sure you've thoroughly checked the contract before you send it out.
-
You should also check that it complies with the law.
-
Send the contract to the buyer after you have completed it.
-
Finally, keep a copy of the completed contract for future reference.
-
Failure to follow these simple rules could result in you losing money.
-
It is easy to put together a great service agreement.
