Title: Observations of Doppler oscillations in a solar prominence

  We report on the observation of Doppler oscillations in a quiescent
  limb prominence. Fourier analysis of the data reveals an oscillatory
  period of 7.5 min, whose phase varies linearly at 16 consecutive
  points (7280 km) along the slit. This yields an upper limit for the
  perturbation wavelength of ≈ 20000 km. Wavelet analysis confirms the
  above period and indicates an oscillation lifetime of 12 min. Moreover,
  the disturbance appears to travel at a speed greater than 4.4 km
  s<SUP>-1</SUP>. A comparison of these results with the predictions of
  some theoretical models is made.

Title: Proper-Motion Measurements of Umbral and Penumbral Structure
Authors: Molowny-Horas, Roberto
1994SoPh..154...29M    Altcode:
  Horizontal proper motions of penumbral structure and umbral dots
  have been measured from a 17-min-long time series of sunspot images
  by numerical techniques. In the penumbra, inflows are seen to occur
  predominantly in the inner region, with an average velocity of 290 m
  s<SUP>−1</SUP>. Penumbral outflows take place mostly in the outer
  part, where they reach velocities as high as 1.5 km s<SUP>−1</SUP>,
  with an average velocity of 500 m s<SUP>−1</SUP>. In the umbra,
  proper motions of 28 bright dots have been measured with an accuracy
  better than 50 m s<SUP>−1</SUP>. The mean velocity of the umbral
  dots is 210 m s<SUP>−1</SUP>. Most of the umbral dots display the
  well-known inward motion away from the peripheral umbra.
