A good day. In the morning we observed the Baikal area. I’m studying fault lines. The first dusting of snow has fallen, and it highlights the terrain beautifully, like morning haze along rivers or in mountain crevices. I measure them with the hand sextant and record the times with Delta, calculating the coordinates of the sub-satellite point so I can later tie the measurements to the flight path. Well, I think, a good bit of work — I’ll calculate and plot several geological structures on the map. We enter the communication session, and Mission Control, without asking us, has occupied Delta with the Stroka telegraph system and is transmitting radiograms. That means all my measurements are wasted. I gave the operator a sharp piece of my mind, telling them they need to ask us whether Delta is free or not. At that point, Kubasov, Ivanchenkov, and Grechko were on the line. They came to congratulate us on the upcoming holiday. We had a good talk. I told the guys that in our family this holiday is a double one — it coincides with my wife’s birthday. They say, “Let us deliver a bouquet of flowers to her from you, she’ll appreciate it.” Then I asked them to include a little note: “Happy birthday. Accept this bouquet from Earth from a heart that loves you, in space.”

At the next session, Yeliseyev came on, saying that everyone is pleased with us. “Good work, going for the record — Ryumin was already getting tired of holding it.” Ryumin also congratulated us on the upcoming holiday and said that TsUP is pleased with our work. It’s nice when your comrades give your work high marks.

After lunch we worked with Delta in mode 67 for autonomous determination of our spatial position. Everything went well, although the SKR spectrometer test showed that not all is well with it.

The day is done. Music is playing for us; we’re listening to new recordings. They sent us good Russian songs.
