Eleventh Workshop Solar Influences on the Magnetosphere, Ionosphere and Atmosphere
Organized by Space Research and Technology Institute, Bulgarian Academy of Sciences, Sofia

Preface to 2020 Proceedings (September 2020)

The Twelfth Workshop "Solar Influences on the Magnetosphere, Ionosphere and Atmosphere" was scheduled to be held from June 3 to 7, 2020 in Primorsko, Bulgaria. Due to the coronavirus pandemic, the Local Organizing Committee decided to postpone the workshop until September. Unfortunately, in September the situation was not better, and it was not possible to hold a face-to-face meeting. Therefore, the workshop was held online. 24 papers with a total of 76 authors from 11 countries are included in these Proceedings.

The Scientific Organizing Committee and the Editors of the Proceedings thank all the participants in the Workshop and contributors to the Proceedings.
