Query: Using Flare-Induced Modulation of Three- and Five-Minute Oscillations
  for Studying Wave Propagation in the Solar Atmosphere   We propose a method for diagnosing the physical conditions in the solar
atmosphere using an increase in oscillation amplitudes resulting from minuscule
solar flares. As an example, we consider a B2 flare, which caused a sharp
short-lived increase in the amplitude of three- and five-minute oscillations in
the lower layers of the solar atmosphere. Enhanced three- and five-minute
oscillations propagated from the lower layers of the atmosphere into the
corona. Such short oscillation trains made it possible to remove the
uncertainties arising in the measurements of the phase and group lags between
the layers. In addition, the amplification of the oscillations that reach the
corona may add to the likelihood of a repeated flare. Studying oscillations in
small flare events has the advantage of exploring the atmosphere in its
quasi-quiet condition as opposed to powerful flares, which cause substantial
and prolonged disturbance of the environment. In addition, small flares are
much more common than powerful flares, which allows one to choose from a larger
sample of observational material.
