Can hi-res magnetometry distinguish between geoeffective solar events?

Can hi-res magnetometry distinguish between geoeffective solar events?

Post by Carbon60 »

A solar storm has been rattling the magnetosphere over the last couple of days, beginning Friday afternoon at around 16:00 Universal Time (refer to my previous post- Solar Storm in Progress).

Apparently, according to Spaceweather.com, this could have been caused by the interaction of fast and slow solar winds http://www.physics.usyd.edu.au/~cairns/ ... node4.html a so called 'Co-rotating Interaction Region' or CIR.

It is the pressure wave at the zone of interaction which can create such geoeffective magnetic storms when this pushes against Earth's magnetic shield (Magnetosphere).

My hi-resolution (one reading per second) magnetometers detected the impact and I was curious to know if the impact signature was in any way different to another geoeffective event, such as a CME.

Below are three charts. The first is the current impact event. This is a snapshot over about a 40 minute period just before and during the initial impact 'spike' (or dip). The second and third charts are taken from CME impact events over approximately the same duration a few days earlier.

I believe that the different types of events show different characteristics, with the CME impacts showing the same characteristics as each other. The CIR event seems to show a dip before the main dip and is less smooth than the CME events. Is this significant???

One set of data cannot be conclusive, of course, but I just found this interesting and wanted to share.

If anyone expert in the field can add any insight to this, it would be most welcome.









Thanks for looking.

Hi Stuart

very interesting and thank you for sharing. I'm not an expert at all. But if you can repeat it in the future and get the same tip in the beginning you can distinguish between the two events :woohoo:

Now this is when it starts to get interesting! the more data you get the more you will start to be able to classify the events. You will shortly become The expert :)

Sure, I just need more data........ :cheer:
