Introducing UKSP Nuggets, short articles highlighting solar physics led from the UK. This is modelled after Hugh Hudson’s Yohkoh Science Nuggets, which ran from 1997 to 2002, and the subsequent RHESSI Nuggets, which started in 2005. As Hugh puts it
a nugget is a lump, especially of native gold or other precious metal. We hope our science nuggets contain some precious substance but since they are written by working scientists, there may be rough spots.
