A small 'cloud' of high density plasma passed close to Earth at about 2100 ut on 22nd September:
I was interested to see how well my magnetometer would respond; especially as after having some serious issues, I had just finished giving it a 'service'.
The top trace is my magnetometer capturing at 150s intervals.
The second trace is the data from the Dourbes professional magnetometer in Belgium.
The bottom three traces show the data from my magnetometer collected at 1 second intervals.
I'm pretty happy with the results - I think that the Apophis-Ra Observatory Magnetometer is back in service
Many thanks to Stu (Carbon60) for his guidance and support in construction of the magnetometer

Wow! superb correlation with Belgium Mike, this magnetometer is working brilliantly did you manage to get the X-class disruptions recently ?

Re: A little cloud of high density plasma...
Thanks Alexandra.
I had imaged the X class event earlier on September 6th:
So, I was quite keen to see what would show up on my magnetometer record a few days later and was excited when I saw a nice peak on the screen of the old computer which collects data from my magnetometer:
BUT.......... when I tried to analyse data from the log files it was total garbage
This was when I realised I had a problem and started to strip down the system to identify the cause
To cut a long story short............... it turned out that the 'export data' settings on my geriatric laptop had been corrupted. On a couple of occasions recently, the computer has shut down to install updates (I can find no way to prevent this - Microsoft will allow me to delay it for a while but still just goes ahead anyway) and has corrupted my settings. I think the time has come to retire the 8 year old laptop
I have it all working again now using another 'semi-retired' Sony laptop and I'm really pleased that it is picking up quite minor events very accurately.

Re: A little cloud of high density plasma...
Excellent, Mike.
I had similar issues recently. My data capture was becoming unreliable requiring me to perform a quick service. All appears okay now, but I missed the X-class main event.
I'll take a look to see if I captured the same plasma flyby.
Glad your system appears to be working well.

Hi Mike,
Same event of the 22nd from Preston here....

Re: A little cloud of high density plasma...
Thanks guys
Not a bad comparison Stu.
Here's our data plus that from a range of UK stations for comparison:
I'm very happy with my results now, other than the 'ramping up' from a low value at the start of the day.
I often get similar effects - thought it was a temperature issue as I had before BUT the temperature sensor shows no more than a 0.4 degree C change over 24 hours and even these fluctuations do not correlate to the 'deviations' from Doubes etc.
Beginning to think it is a 'local magnetic effect' but not sure what??? This thing is so sensitive it could be almost anything!!!!
As you have said before, when I look at the 1 second cadence data it is possible to see passing cars (plus my neighbour mowing the lawn)

Re: A little cloud of high density plasma...
Interesting post.
Don't believe that it will be better with a recent version of windows. They still stupidly update and restart or (recently) popup window with beautiful review message.
The world was soooo simple with computers that run when we want them to run instead of scraping your background running jobs.
Good luck!
