CaK Full Disk 2nd August
It was a very busy day on the sun on saturday, with quite a significant proportion of the Earthward face of the sun being covered in plage or 'a magnetic froth of plasma'. The prominences were also particularly bright on saturday and quite easily visible in CaK wavelengths. Several of the active regions are crackling with flare activity and have a 'beta - gamma - delta' magnetic field that harbours potential for X-class flares. Any flaring that occurred is geo-effective at the moment and would likely hit Earth square on; the forecast potential for geomagnetic storms is as a result quite high at the moment.
