Astra 5A was one of the Astra communications satellites owned and operated by SES at the Astra 31.5°E orbital slot. Launched in 1997 to the 5°E position by NSAB (later SES Sirius, and now a non-autonomous part of SES) as Sirius 2, operation of the satellite was transferred to SES in April 2008 and the craft renamed and moved to 31.5°E to open up a new orbital position for the company for the development of markets in Eastern Europe and the Middle East. Astra 5A failed in orbit in 2009. == Market == The Astra 5A satellite provided two broadcast beams, of horizontal and vertical polarisation, across two footprints, called the CEE (Central and Eastern European) beam and the PE (pan-European) beam. The CEE beam provides reception on a 60 cm dish from Poland to northern Turkey, and the Balkans to the Black Sea, while the PE beam extends 60 cm coverage from Tunisia to the Urals and from the Baltic states to Israel. Countries covered include Armenia, Azerbaijan, Belarus, Bosnia, Bulgaria, Czech Republic, Georgia, Hungary, Iran, Jordan, Macedonia, Moldova, Poland, Romania, Russia, Serbia, Slovakia, Tunisia, Turkey, and Ukraine.〔SES ASTRA "31.5° East" (August, 2007).
