It turns out I'm not mad and that there is a little mini-dipper. It's part of Perseus as I looked for it again this evening and found it. If you look at Cassiopeia and follow the upward stroke of the first V downwards, you come across Perseus, which seems to comprise this little mini-Ursa. I'm glad I noticed that, otherwise I would've thought I was going slightly mad!

Thoroughly pleasant evening at Brian's drinking wine, chatting, smoking (roll ups - a departure for me!) and generally chilling. I even got a second monitor (for edina) out of it so at least I can see what's going on when I need to do stuff, although I don't have a spare kettle lead so I'll have to source one at some point.
