Notification of acceptance


Due to the COVID-19 pandemic the URSI Board, together with the Local Organizing Committee and the Scientific Coordinator, have decided to postpone the 33rd URSI GASS scheduled to be held in Rome from 29 August to 5 September 2020.
We deeply regret the need for this decision, but we have decided that, in the interests of your health and safety and for the success of the meeting, this is necessary. The postponed GASS will occur approximately one year later in late August and early September 2021 and fortunately we will still be able to hold the meeting in the eternal city of Rome.
Further information on the GASS and the postponement of other URSI Flagship Meetings will be provided soon. Authors of submitted papers will be soon contacted with specific information regarding the publishing options of accepted papers.
