Sun outage
Sun outage message on cable television, seen in Singapore, September 23, 2006.A sun outage is an interruption in or distortion of geostationary satellite signals caused by interference from solar radiation. The effect is due to the sun's radiation overwhelming the satellite signal. Generally, sun outages occur in February, March, September and October, that is, around the time of the equinoxes. At these times, the apparent path of the sun across the sky takes it directly behind the line of sight between an earth station and a satellite. As the sun radiates strongly at the microwave frequencies used to communicate with satellites (C-band and Ku-band) the sun swamps the signal from the satellite. The effects of a sun outage can include partial degradation, that is, an increase in the error rate, or total destruction of the signal.
Effect on Indian Stock Exchanges
In India, the BSE (Bombay Stock Exchange) and NSE (National Stock Exchange) remain closed from 11:25 to 12:05 during 'sun outages'. The interference in satellite signals disturbs smooth transmission of data of online transactions, hence these share markets remain closed for the duration of sun outages.
