I relay an observation by Rob H. Mcnaught TSS was very nice. About 1 deg long, just visible to the naked-eye in the twilight at 8 deg elevation due north. In binocs there was a mag 6 point at the top end. The (un)tether was only very slightly curved, but I can't be sure which way. I think it was concave forward. In a dark sky with good phase angle, this will be awesome. It was pretty bloody impressive in 10x50Bs low in the twilight at over 1000 km!
