"Kosmos-2519/2521/2523
---------------------
The Russian inspector
satellite experiment launched in 2017 continues. From Jun 27 to Jul 19 the
host satellite Kosmos-2519 made a series of burns which changed its orbit
from 644 x 659 km to 318 x 664 km. Kosmos-2521 appears to have made a single
burn on Jul 20 to go from 346 x 362 km to 292 x 348 km. Kosmos-2523 remains
in the 553 x 665 km orbit into which it was ejected last October.
