During Solar Cycle 24, our star went through an unusual period of low solar activity. This extended solar minimum was the first during the space age. We are able to explore this extended minimum with an unprecedented set of space-based helioseismic and atmospheric data available from the Hinode spacecraft, SOHO, TRACE and SDO. In addition we have access to historical and contemporaneous data from many ground-based observatories including BISON and GONG. This wealth of data allows us to connect up unusual behavior in the interior to that of the solar atmosphere and in so doing provide a firm foundation for advances in the understanding of the cyclic behavior of the Sun.

The main objective of this Topical Issue (TI) of Solar Physics is to highlight recent findings achieved by a series of Leverhulme Trust sponsored workshops which combined the skills of helioseismologists and atmospheric scientists to probe the Sun from the inside to outside. However, this TI will implement an open policy, so will not be limited to Leverhulme Trust workshop contributions. We also welcome original and relevant manuscripts that were not presented during the workshops.

All submitted manuscripts will be fully refereed. To assist the Solar Physics Editors, Dr Deborah Baker, Dr Rachel Howe, and Prof Louise Harra will act as Guest Editors for this Topical Issue.

We solicit manuscripts on various aspects of solar physics research coupling the various regions of the Sun for inclusion in this TI of Solar Physics. Online submission via the Solar Physics on-line submission system will end on 31 January 2015. Deadlines for submission will be strictly observed and the anticipated publication date for all accepted contributions included in the TI is 31 July 2015. Accepted late papers may appear individually in later Solar Physics volumes.
