Spotted 4 hours ago by Koichi Itagaki at an already surprisingly bright mag 13 C . A tough one from the UK but better further south, Spain perhaps ?

Now also confirmed as a Ia

Now also confirmed as a Ia and so could reach mag 12 or perhaps even a bit brighter at this distance depending on extinction
