Video of the surface of the Sun showing convection in the solar photosphere
Summary
[edit]| Description |
English: 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 Observer: Vasco Henriques and Ainar Drews (University of Oslo, Norway) Date reduction : Vasco Henriques and Luc Rouppe van der Voort (University of Oslo, Norway) |
