CME impact (from AR1990)- magnetometer response
Hi all,
The recent CME from AR1990 arrived yesterday and sparked a G2 geomagnetic storm and beautiful aurora down to lower latitudes than usual.
Here is the response from my magnetometer. Unfortunately, I missed the light show
Thanks for looking.

Re: CME impact (from AR1990)- magnetometer response
I noticed the episode unfurl on the Lancaster site but I think I was too late, I was imaging around 9.30-10.30 and I think I should have missed Warehouse 13 on the TV and gone out between 8-9 instead
I've taken some photos but of some Manchester light pollution I think. I need to have a look tonight.
Well caught Stu, but you need to refine your alert system

Hi Alexandra,
I was out at about 9:30pm and couldn't see anything either. Oh well. Too much light here too.
Hope the pics come out.

Re: CME impact (from AR1990)- magnetometer response
Thanks Walter.
I've now extracted the hi-res data and plotted the impact event in detail. This represents the slice of time that appears as a simple downward spike in the original data (collected at 2.5minute intervals). With the hi-res data (1 second intervals) we can see that the spike is actually more complex, with a couple of 'shoulders' just before and just after the lowest point. It would be interesting to see how this changes from CME to CME.
Cheers
Stu.

Re: CME impact (from AR1990)- magnetometer response
It would be interesting to match the dips with the aurora sightings around the UK. It seemed that most of the auroras were sighted around 8pm which is a long time after the main dip. This would help a great deal with prediction in future

Re: CME impact (from AR1990)- magnetometer response
I dozed off on the sofa on thursday evening and woke around 10 ish, missing the main part, but got this image from around 10.30ish. There is the faintest band below Orions belt through the hyades, but it is very borderline. This is the 3rd time i've seen the aurora from the UK, and after being spoiled by Icelandic auroras on numerous occasions i'm maybe a bit complacent about this UK one...

Re: CME impact (from AR1990)- magnetometer response
Very interesting, Alexandra. There is actually a second substantial downward spike just after 8:00pm (around 8:26pm), which could account for the sightings around this time.Montana wrote:It would be interesting to match the dips with the aurora sightings around the UK.

Here's a plot of 'rate of change' which shows this event more clearly. This is followed by some further turbulence over the next few hours.
Cheers

Looking forward to seeing your time-lapse images from Iceland.

Left in the frame is looking west, right in the frame heading around to north... North is just the other side of the chimney breast - I was poking my head out of the loft window...Montana wrote:Mark, isn't that looking south?

those three bright lights near the bottom of the pic, are they the belt stars of Orion

You can see from this picture why I ditched nighttime astronomy and went over to solar. The middle of the city is not good for stars...

Stuart,
Interesting graph, tell me about your magnetometer setup. Your solar images on Flickr are amoung the most detailed and interesting I've seen.

Hi Phil,
There is a detailed description of the set-up in the tutorial section, which I hope will be of some help.
Thanks for the compliment about my Flickr images. Still learning.....
Best regards
