Thank you Ricci – I’ve added this to my Favourites, noting that Sappho on 11th July 2010 appears to be the first event. 2001SX169 may be too dim for me at mag 17.7 unless it is relatively stationary.
Yes, that is an ineresting list. Do you know if IOTA are taking an interest? I haven't heard anything through them, but it seems like a nice event to observe.
