WEATHER COMMENT: Mon Oct  4 16:25:59 GMT 1999
Cool, clear, light south wind.
Mon Oct  4 16:26:51 GMT 1999	CHIP	 Startup--Initializing new tape
MKIII COMMENT: Mon Oct  4 16:38:41 GMT 1999


>>>> The last observations with MkIII were recorded Thursday September
30, 1999.  The $data/MkIII directory on nahenahe is gone.  Data transfer
from the k-coronameter control computer to nahenahe is strictly MkIV
and all mention of MkIII has been removed.    Scanlog picks up MkIV
file names.  

MKIV COMMENT: Mon Oct  4 16:42:34 GMT 1999
Software changes for MkIV today.  There was a digital wrap around in
I and Q at really low heights, possibly below useful height, but
just in case, the corrector table has been changed for so that the lowest
height has 1/2 the gain of yesterday.
The corrector table now smooths over the hairline positions.  This way
as the hairlines drift during the day, there will not be artifacts frothe correct remaining in the data.
Sky transmission is picked up continuously now so that there should be
fewer glitches at ends of scans.

MKIV COMMENT: Mon Oct  4 17:29:47 GMT 1999
Lost MkIV phasing this scan.  Also lost it twice previously today.
This is seen as the corona going negative.

MKIV COMMENT: Mon Oct  4 18:37:50 GMT 1999
Last two coronal scans run with the guider hat removed.  In real-time
there was no aparent change in "scattered light" as seen in the
intensity to Q crosstalk.  It is still significant at elevated height
and worse in the West.

MKIV COMMENT: Mon Oct  4 18:46:46 GMT 1999
Last pair of scans with guider hat off and with light trap removed.
It isn't much of a light trap as years of sunlight have baked off
all the black anodizing.

MKIV COMMENT: Mon Oct  4 19:02:17 GMT 1999
No changes made an improvement in the -Q at elevated height.  Any
E-W assymetry could be attributed to bright corona in the West.

Sky is REALLY bright.   Scaling of scope trace indicates >40millionths.
There is a signature of saturation in the gif display.
WEATHER COMMENT: Mon Oct  4 23:36:42 GMT 1999
Sky too bright, either thin cirrus or haze from down below.
Shutting down.
