The European Solar Telescope (EST) project consortium is holding an international contest for secondary schools called “The Sun at a glance”. Students from all over Europe are invited to research different subjects related to our star and help us build the EST Solarpedia, an open educational resource about the Sun.
Participants are expected to design an infographic where the Sun is the protagonist.
There will be three prizes:
The teams producing the two best designs, together with their teachers, will win a trip to Tenerife (Canary Islands, Spain) to visit Teide Observatory and the European solar telescopes in operation there.
The third prize will be an H-alpha solar telescope. It will remain the property of the school.
It took exactly two years after instrument commissioning to finally get 1st- and 2nd-light at the very same day with Callisto at IRSOL.
Obviously, the Sun started to get active in terms of radio radiation at decametre wavelength (here 45-70 MHz).
Following the NOAA, Space Weather Prediction Center classification, the instrument observed twice a small group of type III bursts.
Type III radio bursts are a group of fast drifting radio emissions associated with solar flares. These radio emissions are believed to be excited at the fundamental and second harmonic of the electron plasma frequency.
Solar type III radio bursts are an important diagnostic tool in the understanding of solar accelerated electron beams.
They are a signature of propagating beams of non-thermal electrons in the solar atmosphere and the solar system.
Consequently, they provide information on electron acceleration and transport, and the conditions of the background ambient plasma they travel through.
