Radio observing would make an interesting group activity and it’s especially suitable for our climate an it can continue in all weathers. There are a range of projects which can be carried out with varying expertise and on a limited budget. Observing the effect of solar flares is straight forward and John Cook (the BAA Radio Astronomy section co-ordinator) collates observations and writes them up in the BAA Journal.
