Tonight's Tau Herculid's Meteor Shower

Every August, between the 12/13th and 13/14th, my husband and i find ourselves sat on a hill in Exmoor watching the Perseid meteor shower although it usually takes the form of one of us saying 'Wow, that was a good one' to the other who was looking at a different patch of sky.
Usually, the Perseid's with it's 100 meteors per hour rate is the highlight of the year for stargazers but this May we have the Tau Herculid's Meteor Shower which has astronomers jangling their telescopes excitedly as it promise a once in a generation shower to rival the Great 1966 Leonid Storm which threw down 40 meteors per second.  
The Earth is set to plough through a particularly dense trail of debris from the romantically named 73P/Schwassmann-Wachmann (or SW3) comet although there is some concern over how fast the particles are moving, the slower they are travelling the fainter the meteors will be so rather than the bright, colourful meteors of the Perseid's, they could be much fainter but if they are falling at 40 a second, more than enough will be visible or they would be if not for one quirk of fate for us on the British Isles.
In Britain, on the morning of 31st May, the Sun rises at 04:55am so at 06:00am when the Earth's spin takes us face first into the shedding SW3 debris, we will already be bathed in the bright sunlight of the new day which means no amazing Meteor Shower for us here but at least we still have the August Perseid's and a trip to a hill in Exmoor to look forward to, cloud cover permitting.
