#2003 Aug 16	Tohmura, Shinoda, Singh-san

* Singh-san's CCD
  -> alignment has been changed

* determine G.A. for 10830 at the new alignment (by Singh-san)
  4th 5303 <-> G.A.14.872
  -> 2nd 10830 (4th 5415) <-> G.A.15.301

* HeI 10830/SiI 10827(2nd order)
  G.A./filter=15.301/RM90
  slit width=150 micron
  exp.=500 ms (through clods) or less
  no binning

* target
  NOAA0431    S13E03    beta-gamma-delta type

* test exposures

  test data 'test.pmi' exp.100ms  07:01JST c.a.
  test2.pmi (surge?)
  test3.pmi (flare kernel? or mere brightening?)
  test4.pmi (flare kernel? or mere brightening?)

  slit width -> 100 micron, exp. 20 ms
  test5.pmi (flare kernel? or mere brightening?)

  H-alpha monitor -> ha_0001.bmp

* polarimeter setting (by Shinoda-san)

* telescope focusing f=82.0
  occulting disk focus=316.4
  spectrograph focus lambda=?

polarimeter balance OK
exp. -> 50 ms

clear sky!
seeing rather good!

* mk5 trouble? -> recovered by Shinoda-san

* polarimeter obs. of NOAA0431

 1) -50" - +18", 2" step, QUV full set  he1_210...iranai
    +Q, -Q, +U, -U, +V, -V,...  he1_000 - 209
    1 set <-> 30 sec c.a.
    08:52 - 09:25 JST

    ha monitor	09:25 JST c.a.	passing clouds!
		10:00 ha_0004.bmp

    polarimeter balance re-adjusted.

 2) root of surge, slit fixed, QUV half set
    +Q, +U, +V,...  he2_000 - 005 (2 sets)
    1 set <-> 15 sec c.a.
    10:42 -  JST ( being interrupted by clouds )

    ha monitor	10:34 JST c.a. ha_0005.bmp
		10:46 JST c.a. ha_0006.bmp

 3) flare kernel(brightening?), slit fixed, QUV half set (contd.)
    +Q, +U, +V,...  he3_000 - 067 ( 32+a sets)
    1 set <-> 15 sec c.a.
    11:03 - 11:30 JST ( being interrupted by clouds )

    ha monitor	ha_0007-12.bmp

 4) surge?, slit fixed, QUV half set (contd.)
    +Q, +U, +V,...  he4_000 -  (  sets)
    1 set <-> 15 sec c.a.
    11:38 -  JST ( being interrupted by clouds )

    ha monitor	ha_0013-14.bmp (0013 ... slit position)

    bad seeing!

 5) dark & flat
