Zenith-2 encounters

I checked the close encounters between Zenith-2 rockets with
similar orbit planes (they are not as close as they were a year ago)
Since most of them are in orbits near MM=14.14, they will approach
slowly, and might be seen close at a convenient time for you.
The orbital planes of the satellites they launched have also
diverged a bit, but can still give rise to interesting encounters.
I did not check every object against all others, so I may have
missed some close ones.
