<font face="Arial">As I understand the physical format of the new
boards, the housings I've been working on for direct burial will
have to be redesigned. If the intent is for Hyomin to use the new
boards, I'll wait until I can get a sample to design the new
packaging. Dave Witten's old 0.10 rev board which has been
working well over 400 feet of CAT5E fits nicely into a 1 1/4 inch
ID PVC pipe in a vertical position which swaps the Z and X axis
orientations and which I have been using for all of the reported
observations to date.<br>
<br>
Temperature control of some sort to at least 1degree C ....
constant temp oven or direct burial will be necessary to obtain
meaningful readings.<br>

Since our last, I've had to devote time to several
other matters and haven't progressed much toward your
unit. However, that appears to be a good thing since
I was planning to send you the single mag unit I've
been using here repackaged for burial up to 30 inches
and with cable connections that match your present
setup. Along with that, I was building a two
magnetometer unit to do comparisons in my location.<br>
<br>
So, I'll reverse course and finish the two mag unit
for you. The magnetometer adapter boards will be the
same as you're using now the only change being the
second magnetometer and the termperature sensor will
have different addresses on the i2c bus .... you
access both mags on the same cable. Dave Witten will
have to do some program changes to capture both units
but the setup will provide the best arrangement for
comparison of two magnetometers ...... both in the
same local temperature and magnetic environment.<br>

During your run, the temperature
of the 3100 was probably
reasonably constant so your
result is consistent with basic
3100 specs. Keeping the
temperature constant over 24
hours should give you a close
alignment with future JJ station
measurements. Good news.
<br>
I can house your rm3100 in the
same way I did mine or, I think
I have enough extra parts now
from Dave to make one up and
send it down .... possibly drive
it down since you're about 150
road miles from here, which I
can do in three hours.<br>

that it took me so long to
work on the data that was
retrieved from Jenny Jump.
The two sensors (Bartington
and our mag) were placed
inside a solenoid which was
then placed inside a
mu-metal case. Long story
short, there is NO reason to
believe that our
magnetometer behaves in a
different way compared to
the other. They trace the
artificially generated
fields well. The only thing
that needs to be addressed
later is that the given
field was so big that the
output signals were
saturated - the fields
inside the solenoids should
have been decreased to avoid
saturation. My oversight
that I had to leave the site
in a rush. However, both
sensors traced the fields in
the same way. I hope I will
have more time to stay at
Jenny Jump next time to
monitor the signals more
carefully as the NJIT system
has now been fixed. <o:p></o:p></p>

style="font-family:"Arial",sans-serif">Dear John,<br>
Yes, temperature
information was posted a
while back. PNI
initially claimed that
there was no temperature
effect due to the
essentially self
compensating scheme used
for field measurement.
After I measured as much
as a 7-10nT per degree C
tempco in some
controlled oven
experiments and sharing
that data with PNI, PNI
eventually replied that
engineering had measured
a maximum of +/- 2nT per
degree C for the
inductors alone but had
not characterized the
complete sensor.<br>
<br>
The data I have taken so
far is not complete but
indicates that the
tempco (1) may not be
equal on all axes,
including differences in
sign and (2) may not be
assumed to be equal for
any two units and (3)
may not be linear with
temperature, making
algorithmic correction
of the recorded data
difficult.<br>
<br>
Hence, my attempts to
achieve temperature
stabilization to better
than 1 degree C over 24
hours for the recordings
I've been doing (sensor
in a housing that can be
easily buried sub
surface).<br>
<br>
Have also done some
experiments with an
insulated chamber
containing a thermal
mass, equivalent to a
low pass filter, to
achieve stabilization.
<br>
<br>
Another approach is a
temperature controlled
oven set to a few
degrees above expected
maximum local ambient
temp but that requires
power, which complicates
long cable runs.<br>
<br>
At just 19-20 inches
below grade in my shaded
woodlot, 24 hour
temperature stability
has been within 0.7C.
Another 12-16 inches for
the next install should
bring that to a diurnal
variation of perhaps
0.1C in this location.<br>

after 24 hours
to nearly the

not.
Ionospheric
currents
flowing in the
E region
should not
affect Z
exclusive of X
and Y under
most any
geometry I can
think of, so I
wondered
whether the
uncalibrated
RM3100 was
likely causing
this. (I have
never
professionally
calibrated a
magnetometer,
so Hyomin
might need to
comment
here.). In
other words, I
always assume
there is some
measurement
systematic
until it has
been
completely
ruled out
before
assigning it
to geophysical
variation.<o:p></o:p></p>

style="font-family:"Arial",sans-serif">All,
<br>
I was hoping
to record a
relatively
short term
event but
missed one
about 10 days
ago. However,
there was a
good run on
the 12th with
an ~30nT
excursion on
the Y axis
lasting about
an hour. In
the attached
pdf, the three
axes of the
RM3100 again
track the
Fredericksburg
magnetometer
station data
quite
closely. The
RM3100 plotted
data points
are simple
running
60second
averages and
not the more
complex
filtering
algorithm used
by Intermagnet
stations for
their 1 minute
data points.
<br>
<br>
The vertical
axes scales on
all plots are
as close as I
could match
them by eye in
cutting and
pasting.<br>
<br>
I believe the
value to the
right on the
Intermagnet
plot is the
mean for the
24 hour
period. I did
not try to
compute a 24
hour mean.<br>
<br>
One of the
products for
the future for
general
interest would
be a running
plot like
those
available on
Intermagnet.org.
I guess we can
dream a bit.
