Carolina Maiorana succesfully defended her thesis "Geographical
Characteristics and Meteorological Environment of Terrestrial Gamma-ray
Flashes" on May 28th.

There is a new paper on the motion of streamer discharges in unsteady airflow:

- M. Niknezhad et al., 2021. A three-dimensional model of streamer discharges in unsteady airflow. Plasma Sour. Sci. Technol., vol. 30, 045012

As the first of the SAINT PhD students Matthias Heumesser successfully defended his thesis "The origin of Gamma-Ray Flashes in Thunderstorms" on April, 8th.

A new Nature paper:

T. Neubert et al., 2021. Observation of the onset of a blue jet into the stratosphere. Nature, vol. 589, pp. 371-375

As a substitution of the project management course, originally planned for the final SAINT school, we are organizing a project management course on

April, 14th, 9 a.m. - 5 p.m.

April, 21th, 9 a.m. - 5 p.m.
