There’s a nice string of sunspots on the Sun now with active regions 2321, 2324, 2325, 2326 and 2327 all visible. Prominence activity is low in Ha, but there are some fine filaments arcing around the main sunspots and further out on the north limb.

Images taken 18/4/15 12.14 – 12.27 UTC+1 using Coronado Ha PST and CaK PST and DMK41 camera. Processed in Registax 6 and Photoshop CS2.

The Sun 26/3/15 – Active Region 2305 and a large ‘Hedgerow’ Prominence

Active region 2305 is near the centre of the sun and facing Earth which could give us some nice aurora if it flares. The region has a beta-gamma delta-magnetic field which is capable of producing the most energetic X-Class flares and if this area erupts in the next couple of days the ejected material could have a large impact down here.

Imaged with Coronado PST Ha (40mm) and Lunt Solar Cak wedge (100mm) with DMK41 camera.
