21h00 - 24h00; Laurence and Emmanuel (Artis): Observations for project 029-20 continued. Opacities better than expected from the forecasts, with a nice opacity window from 21:00 and 00:00UT with a mean opacity around 0.3, that allows us to complete a whole iteration on sources. Note that the last 30 min spent on the project sources reached low elevations, from 21 to 14 degrees |

Strong indications of atmospheric instabilities from tau225 fluctuations and beam profiles on pointing scans between 00:30 and 1:30. We did two skydips, hoping they could be used despite instabilities. Indication of improvements after 1:30. We launched 2 pointing "probe" scans at high elevation and found reasonable beam profiles. |

So, scans 61-66 haven't appeared yet in the TAPAS archive. At 13:54 local time the telescope decided to move to the zenith for no obvious reasons.
