Comments: More on the desserts today - another delicious yoghurt cake as well as waffles with apricot and blackcurrant jam... We had an earthquake that Nada didn't feel or hear...
We started the night with EFOSC, variable seeing. We changed to SOFI in the middle of the night. Some minor issues right after switching but things smoothed out.
