The Altitude at which Solar-Flare-Induced Ionization is Released
Abstract
Observations of instantaneous frequency and angle-of-arrival changes during solar flares suggest that new ionization is introduced initially somewhere just above the E region--very probably in the height region 120 to 140 km, although even higher heights are possible. This initial ionization may or may not be followed by the generation of ionization in the absorbing D region. The time variation of height at which solar-flare-induced ionization is released, suggests that the ionization-producing radiant energy is initially soft, and then hardens as the flare progresses.
