David,
thanks for posting about this brief opportunity to see this NEO from the UK.
I find it frustrating and amusing in equal measure that the MPC’s ‘Daily Minor Planet’ often tells us about NEO flybys the day after they’ve been and gone. 🙂
I had to smile this teatime as I checked my e-mails and ESA’s 2010 WC9 Close-Approach Fact Sheet arrived in my Inbox at 16:09. Informative but no use for planning a UK observing session.
Thankfully other resources such as the Minor Planet Mailing List and some astro magazines tell us in advance. I recorded 2010 WC9 last night and will add something to my Member Page this evening.
Clear skies,
Alex.
