1 also quoted as 8500W
2 39W seems very low. However, the Boeing / Hughes website confirms this power.
3 Astra 2C was to be moved to 28.2E when 1K was launched. After the destruction of 1K, SES-Astra have announced 2C will stay at 19.2E for the forseeable future. Astra 2C was moved to 28E summer 2007. 2C was relocated to 31.5E in May 2009 to cover for the in orbit failure of Astra 5A
