2D DOCKING ATTEMPT SUCCESSFUL ON 4 JULY 1992 AT 1707 UTC.

During the first pass here in orb. 36500, 1648-1653 UTC, Progress-M13 was still flying autonomously for she still transmitted on a frequency which has to be quiet during the final approach and after docking. Viktor (Savinykh or Afanasyev) on board of the former tracking ship Belyayev tried to get in touch with Mir, but Kaleri asked him to keep quiet for the docking operation was about to begin. Kaleri told TsUP that they did not see Progress-M13 neither visual nor on their screens. So for abt. 1.5 hour I did not know whether Progress-M13 had been docked or not. During the pass in the next orbit 36501, 1823-1841 UTC, the crew reported that the air-seal was perfect. Progress-M13 had been docked to Mir's forward port at 1707 UTC. Viktorenko told TsUP that they would open the hatch to Progress-M13 as soon as TsUP ordered them to do so. TsUP did this and the cosmonauts crept to the hatch and opened it at 1837 UTC. During the following pass Kaleri reported the good state of the Progress-M13: all was clean. Crew and TsUP exchanged congratulations and the crew thanked the specialists on TsUP for the excellent achievement and TsUP's care for the crew.
