Last time I posted this image it had 3.5 hours of data. I have subsequently added another 2 hours of data which I have been collecting when I can over the last two months (the weather has not helped) and will be adding more to in over the next month or so. It is going to need maybe 10 hours or more to bring out all the faint whisps of gas.
