Missed scan no3030 because of pointing and focus check after sunset. Sr did not observe between 11:15 UT and 11:44 UT because of a power glitch that required to make the setup again. High Tsys in BBC01 LSB. |

Receiver power supply fuse blew on antenna. Good data from 308-08:44 onwards following repair. No other known problems. |

Tsys for last channel (8U) incorrect. Tsys calculated with hot/cold loads, preob takes 25sec, start recording 15sec late on each scan, some scans too short, e.g.:
