Not to mention the RADAR

Steve Bosley

Only later did we look at our Radio detection system (after Michael O’Connell of Basingstoke reported that he had captured something)….Our trace is here

I am still trying to understand how to interpret these traces, but even to my eye what is clear is there was a very rapid increase in frequency as the meteoroid hit the atmosphere. The frequency suddenly broadened into a 50Hz bandspread, peaking briefly (at the explosion?) at more than 150 Hz. The 50 hz band persisted for a further 5 seconds or so, before the trace ends with two to three seconds of ‘top notes’. In total, the event lasted around 10 seconds. I’m sure there are experts out there who can explain what all that means !
