5303+6374 corona scan

CCD-A:	6374 3rd	6374 IF	  2x2 bin
CCD-B:	5303 4th	5303 IF	  2x2 bin

GA=14.876
f=51
f_lam=256
target:	west AR


1. long scan  (indivisual mode)

  3" x 100pos,   exp=10s
  slit=400micron
  g1_000 -- 099
  r1_000 -- 099

2. short scan  time sequence
	

	Single Position   Slit verticle to the solar edge
	Slit = 550 micron

	  exp=10s  About 331 frames
  g2_000 -- 330
  r2_000 -- 330

3. Area scans of short area

	Slit = 450 micron
	Step = 5 arcsec
	Scan Positions = 30	; Scan area= 5" x 30"
	Exp. Time 10 sec
	Files are
	g3_000 --046
	r3_000 --046

	H-alpha activity seen in the region of scan from 11 to 13:30
	There is small time gap between *.001 and *.002
	Clouds came at 15:15 jst.
	Files up to *_044 are alright.
