All scans were recorded successfully, but problems with access to the WX parameters meant the antenna reported offsource from 283-2349a to 290-0039 and 290-0235 to 290-0440. In addition incorrect (stale) WX data was reported during both those periods and therafter up until about 07:40 UT with the refraction correction being off as a result.
