Magnetometer
Not sure where to post this one. Is there a magnetometer section on this site?
Given the awful weather here in the UK I've almost given up all hope of seeing the sun again this summer. However, not willing to miss out on the action, I've taken to measuring Earth's magnetic declination local to my home in the North West of England using a home made fluxgate magnetometer connected to my PC. Last weekend was a real treat when the CME from AR1520 struck Earth's magnetosphere. The attached image is a three-day recording of the impact event showing clearly the transient waves and ripples in the magnetic field created by the event.
More to come as we approach solar max!

Re: Magnetometer
Cheers guys.
Happy to provide more info. I'll put something together over the next few days.
Colin, the units are essentially nT, but it is not precisely calibrated, which is something I'm working on. I'm using Lancaster University's magnetometer data on SAMNET as a reference point, calibrating my readings against theirs.
Cheers
Stu.

Re: Magnetometer
Many thanks Stephen.
More to follow. Just doing a bit of a write up on my set-up, which I hope to complete later this week, time permitting.
Regards
Stu.

I am still lost. To me nT would be index of refraction times time.
:thanx:

Nanotesla
Observing the Sun with complex optical systems since 1966, and still haven't burned, melted or damaged anything.
Not blind yet, either!
Light pollution? I only observe the Sun, magnitude -26.74. Pollute that!

Sorry Colin, yes, Nano-Tesla.

Re: Magnetometer
Just to get a feel for this, what would be a change in magnetic declination during a very large magnetic storm?

Re: Magnetometer
Hi Colin,
Sorry, I must have missed this one.
The declination angle is very small, even with a quite strong magnetic storm. We're really only speaking of fractions of a degree on a compass needle generally; more for really large (and rare) storms. There's quite a lot written on the web about this type of thing and there are several descriptions of basic optical magnetometers which will give you an idea of how small the rotation angle is.
Hope this helps.
