The organizers of the 47th EPS Plasma physics conference have reluctantly concluded that it is not possible to deliver an in-person event in Sitges (Spain) from 21st to 25th June 2021. This decision reflects concerns and uncertainties arising from the present public health situation, which will inevitably affect all aspects of conference organization and travel on the relevant timescale. The conference together with its satellite meeting will take place online. The dates of the conference remain unchanged.
