SA: Lee SO: Veronica Others: Mahike, Lisa, Malcolm, Jake, Shan, Shamiel, Dev ------------------------------------------------------------------------ Summary ------------------------------------------------------------------------ We managed two more blocks tonight which would normally be disappointing, but with the recent weather it feels like a victory! A combination of cloud and humidity kept us closed most of the night, and some mirror issues meant we failed to make the most of the gaps in the weather. Good progress was made with the laser comb commissioning during the bad weather.
