G1 Geomagnetic Storm 28th Feb '19

Post by Carbon60 » Thu Feb 28, 2019 7:29 pm

Hi,

A large, wide, coronal hole is spewing high speed solar wind across the chasm, creating a G1 solar storm and on going geomagnetic 'rumblings'.

Here are my data from yesterday and today.

The coronal hole is very wide, so we can expect geomagnetic activity over a few days yet. The intensity depends on the orientation of the magnetic field carried by the plasma which is impossible to predict.

Thanks for looking.

Looks very unsettled! I've had a few alerts ping through now.

Great data Stuart! :hamster:

I got alerts last night too, pity it was the only raining night for a long time. All previous nights have been totally clear, typical.
