The weather observations are made with a Davis Vantage Pro 2 system. The Webcam is a Logitech 9000 Pro.
All times are in UTC (add 1h for British Summer Time). The software used is Weather Display v10.37.
magnetometer is designed to give advance warning of possible auroral activity.
Disturbances of K = 5 or more on the graph signal
there may be such activity. More information about viewing the aurora can be
found here. More details about the magnetometer are here.
The system has been modified to allow use of a third fluxgate sensor, allowing measurement of both E-W, N-S and vertical components.
An experimental Sudden Ionospheric Disturbance (SID) receiver, intended to record changes in the ionosphere caused by X-ray flares on the Sun, is available here.
