This came off the russian space agency site Where I was looking for MAI-75 and never found it .. :)
But did find this:
On Jan. 24, ballistics ops personnel of the Mission Control Center in Korolev, Moscow region, performed International Space Station reboost maneuver. The operation was carried out automatically, and assisted by Zvezda boosters KD-1 and KD-2, which were switched on at 12:01 Moscow time. The operation lasted 150 seconds. The maneuver resulted in additional station acceleration of 2.85mps. ISS altitude became about 5 km higher.
