Press release: March 11, 2001, 09:00 (Moscow time) [06:00 UTC]

The operations sheduled with OC [Orbital Complex] “Mir” for March 10 are
fully complete.

The Complex is in free drift, continues deceleration in the upper
atmosphere.

During the recent communication session the OC “Mir” onboard systems were
checked out orbit radiomonitoring performed.

The telemetry data report: the Complex remains pressurized,the thermal
mode is normal, the onboard systems perform nominal. The Complex solar
array generate enough electricity to support onboad systems and measure
trajectory data.

The next status report is scheduled for March 12 2001.

Trajectory report No 52 – 11.03.2001 – (OC “MIR”)

  • Date: 11.03.2001

  • Flight orbit number (day): 86140(01)

  • Orbit period (in min): 89.398

  • Mean orbit altitude (km): 247.7

  • Daily average altitude decay (km): 1.8

  • Beta angle, i.e. the angle of the
    Sun vector to the orbital plane (in degrees): +31.2

  • Duration of daylight (min): 54.6

  • Solar and geomagnetic activity current parameters:

    solar F10.7 flux: 160

    geomagnetic index Ap: 5

    F10.7 <= 100 -- low level;

    100 < F10.7 < 150 -- medium level;

    F10.7 >= 150 — high level
