TitleSurface of the Sun in H-Alpha light Contact
»Anthony Galvan III DescriptionThe sun's surface is not visible with white light observation. Restricting the wavelengh to the hydrogen-alpha range of 6562.8 Angstroms, one can see the surface of the sun. This image shows sunspots and plages (beaches) on the surface of the sun where cooler regions (sunspots - light areas) are surrounded by much hotter areas.
The bright areas cause solar eruptions or mass solar eruptions. They can cause electrical black outs on earth and play havoc with satellite and radio communications. When a solar eruption occurs the aurora borealis in the polar regions will be come active.
