We headed to the train station on our way to Norfolk in warm sunshine. While we were away the weather changed considerably. We mostly managed to avoid getting wet, but I was mildly concerned that we had left Bartimaeus moored on the side of a river during a time of heavy rain. I occasionally checked the location the onboard systems were reporting, which didn’t seem to be changing. I’m not sure what I would have done if I thought the boat had moved. I kept an eye on other things remotely too. I could see that the batteries were getting fully charged by lunchtime most days, but the overnight low temperature onboard had dropped by 10°C.
