I just spoke with Sergei at 16:46 UTC and asked him if he would try the SSTV today. While he was going to turn it on, he was just about LOS on the east coast. Just before he went LOS, he told me that he would try it on the next US orbit.
The next pass is only a 10 degree inclination, so it will mostly favor the northern part of the US and Canada.
Good luck all, and get you SSTV programs cued up!
