The former represents a slightly hotter region of the corona and the later represents the much hotter material of a solar flare. Hot active regions, solar flares, and coronal mass ejections will appear bright here. The dark areas &#8211; called coronal holes &#8211; are places where very little radiation is emitted, yet are the main source of solar wind particles.

Each wavelength is based on one or two types of ions &#8212; though slightly longer and shorter wavelengths produced by other ions are also part of the picture. Each wavelength was chosen to highlight a particular part of the sun&#8217;s atmosphere, from the solar surface to the upper reaches of the sun&#8217;s corona.<\/p>\n<p>Here on NOSWE site we chose to provide four pictures of the Sun that highlight the photosphere and the outer atmosphere, called the Corona, because these give a good complementary view of the active regions\/sunspots and the coronal holes, respectively, both of which are crucial when considering space weather.<\/p>\n<p>Courtesy of NASA\/SDO and the AIA, EVE, and HMI science teams.<\/p>\n<\/div><\/div>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>HMI Continuum Continuums provide photographs of the solar surface, incorporating a broad range of visible light.
