Impact of solar activity on the signal-to-noise ratio of GPS signal measured by a receiver located in Hawaii on 14 December 2006 (red) compared to what is normally received (blue). The cause was found to be intense radio emissions (called solar radio bursts) from the Sun. These are associated with solar flares.
