winds moved around to the east overnight and are now ENE. CN concentrations are falling probably as the trajectories start to pass more through Bass Strait. Radon concentrations are now around 150 mBeq m-3, CN around 800 cm-3 and CCN @ 0.5% around 100 cm-3. SO2 is still non-operational while the inlet loss problems are being worked on.
