The 15th Conference of the ESPM Series was very successfully organised in the premises of Budapest’s Eötvös-Loránd University in early September 2017. The triennial meeting series brings together the European and a significant part of the international solar physics community for a week of intense interaction and debate that redefines, often reshaping, the field’s state-of-the-art. ESPMs are assigned to a local organizer via a highly competitive bidding process and are coordinated by the European Solar Physics Division (ESPD), a joint Division of the European Physical Society and the European Astronomical Society. The ESPD values highly the geographical distribution of ESPMs, having assigned their venues in twelve (12) different European countries so far.
