There has been a slight hiccup in providing an answer to last week’s mystery object, in the form of the NatSCA 2018 conference.
It’s been a great couple of days of discussion, but it’s not been well-suited to finding time for blogging.
So rather than doing a rushed job, I’ll provide the answer on Monday. I hope you can bear the suspense!

Glad you seem to have enjoyed NatSca. Have a great weekend.
The mystery to me has been, where’s Paolo? Glad you’re back.
