Whereas the wide spreading structureless coronal luminosity extending out from the lower latitudes is due to an accumulation of ionization which reduces the magnetic field to a low value and permits the radiation to blow the particles out to great distances. Thus the polar plumes, prominent during sun-spot minima, are regarded as owing their form to the magnetic field of the sun. Prior to April 28, the spacecraft had been flying just beyond this point.

THE SUN CORONA FREE

The Alfvn point is when solar winds exceed a critical speed and can break free of the corona and the Sun's magnetic fields. Temperatures in the corona the tenuous, outermost layer of the solar atmosphere spike upwards of 2 million degrees Fahrenheit, while just 1,000 miles below, the underlying surface simmers at a balmy 10,000 F. This requirement comes from the radically changing nature of the corona over the 11 year solar sunspot cycle and the bimodality of the solar wind.

Its structure is determined by the coronal magnetic field which is an extension of the solar surface magnetic. The reason Solar Probe will make two full orbits about the Sun is to permit observations to be made in the corona near both solar maximum and solar minimum. NASA instruments can image the Sun's corona at these. The Corona - The ionized elements within the corona (or solar atmosphere) glow in the x-ray and extreme ultraviolet wavelengths. In defiance of all logic, its atmosphere gets much, much hotter the farther it stretches from the Sun’s blazing surface. The solar corona consists of very tenuous plasma. Occasionally larger plasma features, called prominences, form and extend far into the very tenuous and hot corona, sometimes ejecting material away from the Sun. Something mysterious is going on at the Sun. We found that interaction of the coronal streamers with the dust corona can produce molecules and radicals, which are known to cause the resonance fluorescence. By distillation along the lines of magnetic force the particles collect in the lower latitudes of the solar outer atmosphere and by their diamagnetism reduce the magnetic field approximately to zero in this region, leaving a stray field at the poles. The corona is the outermost layer of the Sun's atmosphere where strong magnetic fields bind plasma and prevent turbulent solar winds from escape. NASA’s Parker Solar Probe and the Curious Case of the Hot Corona. The outer atmosphere of the sun is assumed to be composed mainly of ions and electrons which are actuated by gravitation, radiation pressure and the magnetic field of the sun.
