HST suffered a failure of the side A electronics on the CU/SDF (Command Unit/Science Data Formatter) on 27 September 2008. This units handles telemetry from the science instruments. Operations were switched to the side B electronics on 16 October, but two anomalies occurred later that day, affecting the ACS/SBC and the NSSC-1. HST has resumed astrometric observations using the Fine Guidance Sensors.
