1) Holding health plans and providers accountable for providing high-quality health care: Tying things like accreditation, certification, public reporting, and financial incentives (or penalties) to the quality of health care can encourage health plans and providers to deliver the best care possible.
Auroras are indicators of the connection between the Earth and the sun. The frequency of auroras correlates to the frequency of solar activity and the sun's 11-year cycle of activity.As the process of fusion occurs inside the sun, it spews high-energy particles (ions, electrons, protons, neutrinos) and radiation in the solar wind. When they hit the ionosphere region of the Earth's upper atmosphere, they collide with ions of oxygen and nitrogen. 2  The particles impact the oxygen and nitrogen ions and transfer their energy to these ions.
The aurora occurs only above altitudes of 80 km, and infrequently above 500 km. The average altitude for a normal intensity aurora is between 110 and 200 km. The sun radiates all visible colors, which is why sunlight appears white. The spectrum of visible light associated with the aurora is much more restricted. The aurora is caused by charged particles in the solar wind colliding with atmospheric atoms and ions.
