Location: Gloucestershire, UK Details: Here is something a bit different - a large "five star" tidal bore on the river Severn in Gloucesetershire, UK, caused by a large spring tide and the funneling effect of the Severn Estuary causing a large wave to surge up the river against the flow. There was a carnival atmosphere with hundreds of spectators watching and surfers risking life and limb to ride the bore ! News organisations also covered the event extensively here. This is all down to our Moon of course so I hope it qualifies as space weather !
