Coronal holes and fast flowing solar wind emanating from them over the month created periods of bright aurora as the Sun rotated, periodically sweeping the wind in our direction. The ebbs and flows were recorded on my magnetometer and are shown below as 'rate of change' over time.
Generally we are seeing a reduction in solar activity in terms of sunspot numbers and on December 1st the interplanetary magnetic environment was particularly 'settled' between coronal holes. Just how quiet can be seen below and in comparison with a recent G3 storm in October plotted to the same scale.
.......and a G3 solar storm
Thanks for looking.

Re: November magnetometry summary
That's quite a difference between quiet and active Stu! The coronal holes seem to opposite each other hemispherically given there's roughly a fortnight between them. Interesting data!

Re: November magnetometry summary
Really nice data Stu these coronal holes seem to time themselves perfectly with periods of cloudy weather in the UK

Re: November magnetometry summary
Many thanks Mark/Alexandra.
Even with clear skies and a decent G3 storm I still haven't seen the aurora from home! Mind you, my view north is really bad as it looks over in the direction of the adjacent town, so the sky is filled with light pollution and there are too many trees!
Good spot, Mark, approx. half a rotation apart.

Hi John,highfnum wrote:is a quiet day usually that flat?
Don't forget the scale has been adjusted to match that of the G3 storm, so it looks particularly flat in this comparison.
