This is the oldest still active EORSAT - a Russian Electronic Ocean 
Reconnaisance SATellite. For many years, a constellation of two or
three have been operating, maintaining their relative positions of
30 minutes difference (though usually in two separate orbital planes)
to about 10 seconds precision. The latest one, #24670, is passing
30 minutes before #23748.

The one before that, #23596, has been lowered from its 15.52 MM
orbit and will decay within about two months. At perigee it will
be even brighter than its brothers.

Ted Molczan lists them as 6.0 m "spheres".
