Description: Main Objective: The objective of this project is the measurement of the magnetic field around and in explosive granules at high spatial resolution. Scientific Justification: This type of analysis has already been conducted using data from Sunrise / Imax (J. Palacios et al. AandA 2012 537, 21) but for very short time periods (18 and 21 minutes). A combination of Hinode SP (IQUV) observations and IRIS Slit Jaw at 2832 Angst. during at least 6 hours will allow us to study the relationship between exploding granules and the magnetic field and also their link with Trees of Fragmenting Granules (TFGs). Such a sequence will give us access to many successive explosions which is important for understanding the number of explosions necessary to concentrate the magnetic field at the edges of these explosive granules. These explosive granules are the most dynamic elements of the solar photosphere and contribute to their development through the formation of a ?Tree of Fragmenting Granules" (granules families) whose actions are related to magnetic network formation in the quiet sun (Roudier et al. AandA April 2016
