I guess you found what you were looking for. But as far as I know, that's probably the only thing going down there. People tend to do their thing in the icy place in the months from maybe November to March, which is the closest thing to summer.
The Russian in Vostok said the temp there gets down to -70C. Cold indeed.
There is a story about when my friend Gwen visited me and we tuned around, finding the guy working one station after another, high turnover to give as many contacts as possible. I asked Gwen to call him, which she did, and he responded immediately, giving her a strong signal report. She thanked him and said goodbye. Not so fast, sister! He was so thrilled to work a female that he wouldn't let her go. He kept describing his situation. She kept saying goodbye but he persisted. Meanwhile the crowd had to wait for him to sign off with her. I was chuckling seeing this, and it was a memorable experience. I don't know if they exchanged cards or not.
