Sun Outage is a degradation or temporary interruption of satellite signal caused by solar radiation. In these moments satellites occur to be in between the Sun and the Earth, producing with their shadows an invisible eclipse. Satellarium II shows these astronomical events through a variation of visuals and sounds in the room in which it is exhibited. The installation consists of a set up of multi channel surround speakers and graphics projected on a disk above the viewers, representing the fragment of the visible sky from the location of the artwork. Visuals and sounds are based on real time tracking of the satellites position and magnitude (brightness of a satellite as it appears in the night sky from Earth). The gradient on the background of the projection represents the sun and it is related to its real-time position in the sky.
