It’s nothing serious, just a stuck solar array. Normally, this would pose a problem for the vehicle and crew, as the Soyuz took two and a half days to reach the outpost. However, new procedures have enabled same-day rendezvous for almost every mission the last two years.
The spacecraft has more than enough energy stored in batteries to reach the station. The situation will make for some interesting pictures later tonight once it gets within visual and photographic range.
I wonder how this will affect the vehicle’s capability to return the crew five months from now? I believe the spacecraft is turned off while hooked up to station umbilicals, so there probably won’t be any adverse affect down the line.
