- 06:15 UT Noticed that the humidity reports in wx are broken (all 0% @ ~20C) - spoke to JMc. It's a known problem, and the humidity sensor needs replacing. (Bryn)
- It looks like this issue has been present all experiment - with the humidity sensor reporting either 0% or 100%.
- Error seems to have occurred 207/10:40:00- the wx reports have had intermittent normal reports, with the rest being either 0% or 100%. This experiment, only 0% or 100% have been reported by wx
