Room temperature: 21.0 to 22.6 °C
Due to a failure in the instrument used to record the atmospheric pressure, the atmospheric pressure was not recorded. A review of historical atmospheric pressure data over a twelve month period shows the atmospheric pressure as 95.79 to 103.93 kPa at Harlan Laboratories Ltd, Shardlow, UK.
