              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
The night started clear but had gradually increasing clouds, until by second half it wasn't possible to get usable data.  Radar echoes were also heading across the basin by then, so we closed and were unable to open for the rest of the night although we didn't get any actual rain.
Despite a few clouds, APOLLO was finally able to run with the new calibration system, a big breakthrough.
