There seems to be some discussion as to exactly what the 'Light Bridges' are that divide large sunspots such as the one that dominates AR11236 http://www.spaceweather.com/archive.php?view=1&day=19&month=06&year=2011 However, from my perspective, looking at this picture, in this instance, it is quite clear that a 'Light Bridge' is just a filament that sits over the top of a sunspot. It appears light against the black of the sunspot core, however either side it can be seen to extend as a dark filament hovvering above the brighter solar disk.

Sadly today was dominated by cloud and only intermittent gaps, as such this is the only capture of note that I managed. Visually the sun was very impressive with plenty of prominences all around the limb. The filaments showed quite a bit of subtle change as the day went on.

Hopefully the 'British Summer' will improve from the cloud and rain of late and I will be able to get somemore views in soon!
