ESPD Media of the Month: March 2020

Posted By Tiago Pereira, Wednesday 4 March 2020

We are pleased to announce that the winner of the ESPD Media of the Month contest for March is Luc Rouppe van der Voort (University of Oslo), with the following movie of quiet sun granulation observed with the Swedish 1-m Solar Telescope:

Description: Movie of the solar photosphere observed with the Swedish 1-m Solar Telescope (SST) on La Palma, Spain. The movie shows solar granulation which is a result of convective motions of bubbles of hot gas that rise from the solar interior. When these bubbles reach the surface, the gas cools and flows down again in the darker lanes between the bright cells. In these so-called intergranular lanes, we can also see small bright points and more extended bright elongated structures. These are regions with strong magnetic fields. Instrument: Swedish 1-m Solar Telescope / CHROMIS wideband (wavelength 395.0 nm) Center coordinates: (x,y)=(36",-91") Duration: 01:08:22 hour:min:sec. Observers: Vasco Henriques and Ainar Drews (University of Oslo, Norway) Data reduction: Vasco Henriques and Luc Rouppe van der Voort (University of Oslo, Norway)
