Brushed aluminum rectangular board with rounded edges, 4 x 8¾ inches (602 x 222 mm), 9-column table for plotting navigational parameters incised and lettered in white, two velcro strips to underside. Last three columns rubbed, verso lightly scratched. Provenance: Cosmonaut Anatoly N. Bereznovoy, with the first five columns filled in by him in pencil, and his signature in black marker; Sotheby's Russian Space History, 1996, lot 271. A plotting board used by Berezovoy to plot calculations for orbits 2093-2097 while aboard Soyuz T-5. It provides, in Moscow time, the time of the space craft's entry and exit from the earth's shadow, the time of firing and duration of the engine firing during an emergency descent from orbit, prime radio frequency times with earth, and the number of the orbit. A handwritten provenance letter in Russian by Berezovoy reads in part: [trans] "THIS PLOTTER WAS FLOWN IN SPACE FOR 211 DAYS: FROM THE START OF THE SOYUZ-T5 SS ON MAY 13, 1982 TILL THE LANDING OF THE SOYUZ-T7 SS ON DECEMBER 10, 1982. AT THE EXCHANGE OF THE SPACE SHIPS WITH THE VISITING EXPEDITION (L. POPOV, A. SEREBROV, S. SAVITSKAYA) I BROUGHT THE PLOTTER FROM SOYUZ T-5 ABOARD SOYUZ T-7 AND ADJUSTED IT TO THE CONTROL PANEL... A. BEREZOVOY."
