Re: Magnetometer Project
How far do you need the magnetometer to be from buried electrical lines to achieve acceptable results?

Hi Stuart
as soon as I have reached the status "retired" I'm after it

Re: Magnetometer Project
After a mere 8 days.............. the trace seems to have stabilised at about 4000Hz having started at about 3400Hz when the temperature was fully controlled:
Yesterday's trace was pretty good with no obvious sign of 'upwards creep'

It will depend on the current flowing through them as this will drive the local magnetic field. My magnetometer is about 5m from my house and it doesn't appear to be affected by normal domestic power systems. I wouldn't like to second guess your situation. I would just suggest that the further away the better.
Regards

Re: Magnetometer Project
Mine is buried about 7m from the house but only about 2m from the power distribution box for my observatory. I have spent a couple of 3-4 hour sessions in the observatory drawing power for mount, computer and a 400W heater with no obvious deviation on the magnetometer trace.
However, as far away as possible makes sense!

Re: Magnetometer Project
Thanks guys.
I'm glad I gave it time to settle down but still baffled why it took 8 days!
Fairly happy with the results at the moment as it seems to capture all the 'significant' events - just waiting for a BIG one now.......

Re: Magnetometer Project
Latest update..................
Things seem to have stabilised nicely over the last few weeks and I am now getting data which compares rather well with published results.
The last couple of days have been quite active with swings of 60 to -60 nT
One interesting point - look at 10am on the 17th and you will see a (relatively) big dip in temperature caused by me leaving the patio doors open for about 20 minutes while I was setting up my imaging gear on the patio. Shows just how easy it is to de-stabilise the system (even in a thermostatically controlled box) and, even though it didn't seem to distort the magnetic data too much, a small drop in the output can be easily mapped to the 0.4 degree drop in temperature

Re: Magnetometer Project
That is correct Alexandra.
I must say that I'm very surprised how my £200 'lash-up' performs so well in comparison with professional stations which I assume have somewhat larger budgets

Re: Magnetometer Project
Nice one, Mike.
I had some issues this week with a water leak in the garage and had to use a heater to help dry things out. Needless to say, the temperature change sent my data haywire for a period. Back to normal now....thankfully.

Re: Magnetometer Project
The next step forward for this project is advanced elements of thermal stabilty...
Sounds like it should have been a textbook I read for my A-levels...
