A total solar eclipse is the most spectacular and awe-inspiring astronomical phenomenon mostpeople will ever see in their lifetimes Even hardened solar scientists draw inspiration from itThe eclipse with 2 minutes totality in the early morning of 14 November 2012 (local time)drew over 120 solar researchers (and untold thousands of the general public) to the smalland picturesque resort town of Palm Cove just north of Cairns in tropical north QueenslandAustralia and they were rewarded when the clouds parted just before totality to reveal astunning solar display

The eclipse was also the catalyst for an unusually broad and exciting conference held in PalmCove over the week 12ndash16 November Eclipse on the Coral Sea Cycle 24 Ascending served

as GONG 2012 LWSSDO-5 and SOHO 27 indicating how widely it drew on the varioussub-communities within solar physics Indeed as we neared the end of the ascending phase ofthe peculiar Solar Cycle 24 it was the perfect time to bring the whole community together todiscuss our Sunrsquos errant recent behaviour especially as Cycle 24 is the first to be fully observedby the Solar Dynamics Observatory (SDO) The whole-Sun perspective was a driving themeof the conference with the cycle probed from interior (helioseismology) to atmosphere (thevarious lines observed by the Atmospheric Imaging Assemble (AIA) aboard SDO the severalinstruments on Hinode and other modern observatories) and beyond (CMEs etc) The qualityof the presentations was exceptional and the many speakers are to be commended for pitchingtheir talks to the broad community present

These proceedings draw from the invited and contributed oral presentations and the postersexhibited in Palm Cove They give an (incomplete) snapshot of the meeting illustrating its broadvistas The published contributions are organized along the lines of the conference sessions as setout in the Contents leading off with a provocative view of Cycle 24 thus far from Sarbani BasuOther invited papers presented here include an appreciation of Hinodersquos view of solar activity asthe cycle rises by Toshifumi Shimizu a first taxonomy of magnetic tornadoes and chromosphericswirls by Sven Wedemeyer et al an analysis of HinodeEIS observations of transient heatingevents a timely re-examination of solar dynamo theory by Paul Charbonneau an exciting teaserfor the solar potential of the Murchison Widefield Array now operating in Western Australia bySteven Tingay et al an overview and critique of the state of nonlinear force-free magnetic fieldextrapolation theory and practice by Mike Wheatland and Stuart Gilchrist and a masterfulreview of atmospheric MHD wave coupling to the Sunrsquos internal p-mode oscillations by ElenaKhomenko and Irantzu Calvo Santamaria The many contributed papers published here are noless exciting

All papers have been refereed to a high standard The editors thank all the referees drawnboth from conference attendees and the wider community who have taken their tasks veryseriously and provided very detailed and helpful reports Nearly all contributions have beensubstantially improved by the process

We must also thank our financial sponsors Both the Global Oscillations Network Group(GONG) and LWSSDO were generous in their support as were the School of MathematicalSciences and the Monash Centre for Astrophysics (MoCA) at Monash University Melbourneand the Centre for Astronomy at James Cook University Townsville The Local OrganizingCommittee and the many students who assisted before and during the conference also deservehigh praise for facilitating such a memorable meeting
