After USA 245 raised its orbit a few kilometers on March 5 the
orbits of USA 245 and Kosmos 2542 were not synchronized
anymore and these satellites slowly drifted apart. Since
April 22 Kosmos 2542 is gradually lowering its orbit. Its orbit
was 372 x 913 km but now it is 331 x 911 km. If it remains in
this orbit, its distance from USA 245 will temporarily decrease
to 139 km on May 1.

Meanwhile Kosmos 2543 remains in its 589 x 859 km orbit.
Every 4 days its distance from USA 245 reaches a minimum.
On April 27 this minimum wil be only 30 km.
