Hi, Further info on the Znamya 2.5 "experiment" from the Progress M-40 can be found at: http://www.space-frontier.org/PROJECTS/Znamya/ The 24 hours experiment is planned to start sometime on Feb 04 after Progress M-40 detaches from Mir. The location/cities involved in the sun reflection experiment have not been announced yet but my guess is northern Russia during those terminator passes if the weather is cooperative on the ground.
