Hey Owen,
yes on the 1020 flight out form LHR.
Antes,
If you were originally asked if you would mind attending in August and said yes then you should have been invited out now if not expect to hear something for November I should think (I think it was first come first serve for this early one). Don't Panic! it's obviously quite a busy time for them so wouldn't worry if you don't hear anything for a bit.
