A test of the FITSAT-1 LED optical beacon that took place on December 11 GMT over Japan was successful.

On December 13 at 22:10:30 GMT FITSAT-1 will be using its optical LED beacon to flash a message in Morse Code over the British Isles and Europe which, cloud permitting, should be visible using binoculars. Further information is at

The FITSAT-1 CubeSat was developed by students at the Fukuoka Institute of Technology (FIT) in Japan. As well as the optical LED experiment the satellite carries several amateur radio payloads: a CW beacon on 437.250 MHz, a telemetry beacon on 437.445 MHz and a high-speed data downlink on 5840.0 MHz.
