Further geomagnetic unrest

Post by Carbon60 » Tue Aug 21, 2018 9:13 pm

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 in Iceland.

Excellent Stuart, let's hope you spot something coming from this CME in the next day or so.

Thanks Alexandra. We'll see if the CME has any measurable effect.

You're seeing more action than me, nothing but cloud so far on a night. Frost forecast for the weekend so maybe that will increase my chances. I need to stay awake too - at the moment i'm sleeping for 10 hours straight, missing the brief darkness. If things do clear up i'll have to set an alarm I think.
