The winner for 2015 is ...(drrumm rroll)... Alexander Shulevski. Alexander presented a LOFAR movie of the entire sky using only the super-terp LOFAR stations during a significant thunder storm. The associated lightening discharges are clearly seen in the movie, including many near-simultaneous multiple events - see: http://www.astron.nl/dailyimage/pictures/20150721/movie.gif
Also by a tradition of sorts, the winner of this award receives a bottle of Jameson's Irish Whiskey (see image above*). The Jameson distillery is very well connected to the world of radio science - born in Scotland, the famous distiller Andrew Jameson (1783 -1856) was the father of Annie Jameson (1840-1920), and Annie was the mother of one Guglielmo Marconi, Nobel prize winner in Physics (1909), and the father of wireless (radio) communication!
