This region of the sun continues to show lots of activity, and as such the only way to capture it is by doing a mosaic. This is 6 frames taken with the 127mm PST mod at 1900mm fl with the DMK31. In the bottom left corner new region S1850 [S31E07] emerged quickly and has many spots. If the region develops further minor M class flares will become possible.

AR11543 9th August
Lots on intricate detail in this image - i really like the lightbridge and the little spotlets!
AR11542 C8.4 Flare 9th August
I managed to capture the tail end of this c8.4v flare from this active region. It has polarity intermixing and is likely to produce further low level C class flares. A minor M class flare is possible.

This pair of active regions quietly march towards the suns limb. Dying sunspots...

ar11538, ar11540 and the Mega Filament - 8th August
Over the past couple of days a mega filament has been visible on the surface of our star. This cool ribbon of plasma floats above the main hydrogen alpha layer held aloft by magnetic fields. It stretches further than the earth to moon distance. It is also joined by a series of resonably active regions and their accompanying spots.
This image is a 6 pane mosaic taken with the 127mm SS @ 1900mm DMK31. It represents quite an achievement for me as i've been doing considerable work to minimise the sweet spotting associated with the PST etalon. Given that 6 panes are able to be stitched together seamlessly i'm happy this has been achieved.
ar11542 8th August
This new active region seems to be popping and crackling with activity and could put on a decent show for us in the coming days. 127mmSS @ 1900mm DMK31
