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).
