Description

The fine granularity across these solar images are “Granules” on the protosphere - the tops of convection currents or thermal columns of plasma (aka Bernard cells). Each granule is around 1500 km in diameter, have bright centres due to hotter rising plasma and darker rims due to less hot descending plasma.

The larger features are dark Sunspots (2767), while the associated light-coloured facula are where additional sunspots are likely to develop. If you tap on the right hand image you’ll see the earth I have inserted for approximate scale.

Imaged Sunday 02-08-2020. The front end of the telescope is masked with Baader Astro Solar Safety Film (which looks like Al-foil) that permits 1/100,000 part of the suns light into the telescope, so as not to fry my camera electronics.
