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   Time of altitude Hav ~ 220 km: 20.03.2001 +2 days / -2 days Re-entry prediction with consideration of 15% deviation from solar flux activity value: 27.03.2001 +4 days / -3 days Date of the orbit parameters calculations: 10.03.2001 Renewed information is expected on 12.03.2001 at 01.00 p.m. DMT. -- Andrew Yee ayee@nova.astro.utoronto.ca
