Hida DST Ha Observations on 28-29th April, 2004 (UT)

  1. Observational summary.

    Start End X Y P r(DST) p(DST) Vertical Spectrograph & Note
    21:59 22:01 800" -627" 239 --- 215 Original Target had been disappered before the start of the observation.
    23:08 02:37 --- --- --- --- --- The prominence on the east limb (Target-1).
    Spectra of H-alpha, beta, gamma, He D3, Ca2K, and Ca2H lines were obtained by locating the slit at the selected three positions on the prominence.
    05:20 06:39 --- --- --- --- --- Another prominence on the east limb (Target-2).
    Spectra of H-alpha, beta, gamma, He D3, Ca2K, and Ca2H lines were obtained by locating the slit at the selected two positions on the prominence.
    Start/End = The start/end time of the sequence (UT).
    X/Y = The center of the target region (arcsecs).
    P = The polar angle (measured from the solar north).
    P(DST) = The DST polar angle.
    r(DST) = The distance between the center of the target region and the sun-center.
  2. The target regions

    H-alpha full disk images (6562.81A) showing the target regions.
    Both images were obtained with the Flare Monitoring Telescope (FMT).
