Again: very frustrating! The cloud cover was patchy and rapidly-changing: it thickened in the south just at the wrong time, obscuring the Space-X Dragon as it made its final pass before returning to Earth. Interestingly, the online sources I use for the timings of various astronomical events all published different data for Inspiration, so I might not have seen it even had the skies been clear!
The time outside wasn't completely fruitless: the Moon and Jupiter were close in the south east, and just after 8.00pm the International Space Station passed over them. The whole time I was observing, several Hedgehogs snuffled and grunted around the borders: no need for slug pellets in our garden!
