Further geomagnetic unrest

Earth remains within fast flowing solar wind originating at two large coronal holes, creating further geomagnetic unrest. The wind has been ebbing and flowing over the past 9 days, flipping northwards and southwards, creating intermittent displays of the aurora. Hopefully something for Mark T to see...

Re: Finally some magnetic activity Aug 16th 2018

Good record Stu! There was the faintest of activity on Thursday in Reykjavik but nothing worth bothering about. Last night was clear up here in the north, and despite an early night with the best of intentions to get up and check things out slept all the way through and here we are in the light of ...

Re: AR2718 Sodium and Ha

Excellent images, Franco. For me every imaging session seems like a new experiment; there's always something subtly different ;).

Re: 08Aug Disk: Spectral sweep through H-alpha.

Excellent work, as always, Peter. Very helpful to see the sweep like this.
It's interesting to see the various subtle Doppler effects within the filaments as the sweep progresses through the wavelengths.

Finally some magnetic activity Aug 16th 2018

There has been relatively little magnetic activity to speak of in recent weeks, but last night all that changed.... a bit. Fast flowing solar wind from a large coronal hole reached Earth in the early hours of Aug 16th, sparking beautiful aurora for those lucky enough to see them. My magnetometer pic...

Thanks, Alexandra. I agree with you, but it really took quite some effort to squeeze out every drop of data with minimal noise. It's so difficult when the seeing conditions don't cooperate.
