The Sun in Hydrogen-Alpha
Until the turn of the century, the only times when the inner solar atmosphere could be observed were the fleeting moments of totality during eclipses of the Sun, when the whole of the solar corona and the prominences on the Sun’s limb are viewable. Since the advent of the spectrohelioscope and sub-Ångström filters, each observation can now become a total eclipse of its own.
