On Mon 13th May we were fortunate to have Andrew Thomas of the UK Radio Astronomy Association give a fascinating presentation on amateur radio astronomy. He covered history, practical observing, geophysics and the sun, and several projects/kits available to the amateur radio astronomer. We had experienced the effects of the solar storm that had occurred only a few days previously – it wiped out the first day of our operations at Nutley Windmill. Andrew added some extra slides on measurements of the storm taken by his instruments, including an impressive graph of his magnetometer signals (shown below) – clearly illustrating the strongest magnetic storm for 20 years. Andrew is not an amateur radio operator, but there is obviously a cross-over between his area of interest and ours.
