ESPD Media of the Month: June 2020

Posted By Tiago Pereira, Friday 12 June 2020

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

Description: The movie shows the main sunspot in active region AR 11084 observed with the Swedish 1-m Solar Telescope (SST) on La Palma (Spain). Sunspots are regions with strong magnetic fields. The central dark area, the umbra, has the strongest and most vertical magnetic fields. The dark umbra is surrounded by the filamentary penumbra where magnetic fields are more horizontal. Note that the black line in the top measures 10,000 km on the Sun. Instrument: Swedish 1-m Solar Telescope / Blue Tower wideband (wavelength 395.4 nm) target: sunspot in AR11084 (x,y) = (59",-414"), 2-Jul-2010 movie duration: 1 hour.
