- | * 1530UT - Experiment started ok (Prad) | + | |

- | * Issues with very large clkoff measurement, auto correlations, configuring dbbc. Have restarted / rebooted DBBC, mark5, hobart etc. Warren will look at it in the morning. | ||
- | * 0537 - Experiment resumed after dealing with multiple issues. DBBC was in unusable state, apparently due to a fault in the 10 MHz reference cable. Also investigated RF/IF system following up on recentr non-detections. Found a failed cable compensator which has been bypassed. (JMc) | ||
- | * Ongoing issue - No valid Tsys readings. Origin unclear. (JMc) | ||
