Thanks Richard – a timely (and indeed salutary!) reminder that if one is going to look for close approaches of minor bodies it might be a good idea to make sure your ephemerides are up to date! On investigation, mine were not. Having updated them from the MPC data (and checked them using Solex 11), I find the same result as given in your post.So, as that well-loved radio programme used to say: "I’m sorry, I’ll read that again – I make the closest approach 10arc-sec on 5th July"!!
