There was much to see on sundays sun, alas passing clouds made any longer imaging runs quite difficult. Still, this 2 pane mosaic has turned out nice, and was taken with the 100mm PST mod at 2000mm focal length using the DMK31 camera.

The first proper airing of the 100mm PST mod this year at 2000mm fl with the DMK31 camera of this crackling active region...

The sun is seething with energy at the moment; loads of active regions on the disk are sending charged particles hurtling towards Earth resulting in aurora borealis even visible from the UK - more to follow on this!

Hoping For Aurora's - 13th February

The weather may well be blowy in the UK at the moment, but the Sun also has a strong solar wind blowing too pretty much square on to Earth.  On february 12th the sun threw off a Coronal Mass Ejection in an M-class flare from sunspot AR11974.  This CME follows on closely from 2 others that left the sun on 11th february, with all 3 CMEs hitting Earth in quick succession this could well spark moderately strong geomagnetic activity on february 14th and 15th.  Fortunately for me this is when I travel to Iceland, and with clear skies forecast in Reykjavik on these evenings I hope to be able to get some good photographic prospects.  Stay tuned for updates...
