By lunch time on the second day we got the antenna into tracking mode. The photo shows the antenna pointing towards the Sun. The antenna pointing can be updated as often as every few seconds, therefore enabling us to continuously track the Sun from sunrise to sunset.
All the control and data-acquisition electronics are housed in a large weather proof metal box that is connected to the Rosse Observatory control room. In a few weeks time, we'll be able to communicated with this from the comfort of our offices in TCD.
Following a good builder's breakfast (sausage, pudding, eggs and rashers all in the one bread roll!), we fired up the control PC and started testing communications with the antenna drive motor and Callisto receiver. After some minor crossed-wires, the electronics appeared to be working well.
