In addition to regular online meetings to discuss science and public outreach activities, the WaLSA Team aims at having one-week face-to-face meetings once or twice a year, based on extrenal grants.

Meeting # 1

The first meeting of the WaLSA Team took place at the University of Oslo (Oslo, Norway), between 7-11 January 2019, as a "Rosseland International Team". The entirely interactive meeting was aimed at improving scientific knowledge and stumulating new research objectives under the proposed "umbrella topics" in the field of MHD waves in the lower solar atmosphere. From the challenges raised during the meeting, several new (original) science projects were created. See below (the accordion menu) for more information about the meeting.
