BIO Space Sciences
By the end of August, in southern Greenland, if weather conditions come in just right, the northern lights will be in plain sight. The event will be broadcast live via internet from August 23 to 28. Polar Auroras are caused by the collision of highly energetic particles from the Sun (solar wind) reaching Earth’s atmosphere. These particles are directed by the Earth’s magnetic field, thus entering only by the North Pole (Aurora Borealis) and by the South Pole (Aurora Australis).
Light emission is produced in the high altitude atmosphere due to the collision of the solar wind consisted mostly of electrons against oxygen atoms which originates those greenish tones we are so familiar with.
The best place to observe this phenomenon is on the circle around the magnetic North Pole. And since the magnetic North Pole doesn’t match the geographical North Pole (which is actually placed northwest from Greenland, near to Filesmere island), one of the best observation platforms would be in southern Greenland.
Live Online Broadcasts and Reruns
A daily connection, if weather conditions allow it, between August the 23rd until the 28th, 2013, from three emplacements in Greenland. As pointed out, weather conditions may change the broadcast timing. This broadcast will be transmitted at two levels:
For one hour, a camera (black and white) will look up to the sky in order to transmit a video sequence of the Aurora. Retransmissions will be available at the GLORIA portal live.gloria-project.eu and sky-live.tv.
Every night, the website will be updated with the images obtained with the Canon 5D Mark II (color) cameras, identical lens (separated by 1km minimum and 50kms maximum). Images will be available (on the web) for the educational proposal previously arranged.
GLORIA in Chile
This is a great opportunity for the Chilean people to see something they don’t naturally have over their sky. The astronomer from Universidad de Chile and researcher at the Centro de Astrofísica (CATA), José Maza is the scientist responsible for the GLORIA network in Chile: ‘GLORIA is an international project tremendously ambitious. The team is made up of astronomers and engineers from different parts of the world who want to take –literally- the outer space to home computers and mobile devices available to anyone. In Chile, specifically on the Cerro Tololo hill, we have CATA 500, a telescope astronomers hope could be soon embed to this network.’
