The extrapolated separations in time for UT midnight tonight, i.e. June 12 00:00 UT, are A to D 15 secs, and D to E 4 secs. The position of the outlier C depends on the position of the observer, but it is likely to be seen trailing E by a few seconds. Its orbit hasn't changed since June 2, and without further manoeuvre it will trail an additional 6 secs per night. David Brierley.
