Human Factors
While working the satellite position I vectored Aircraft X into a 2;800 ft. MVA (tower obstruction) at 2;500 ft. I noticed issue just after the aircraft entered the MVA and issued a heading to avoid the depicted obstruction and on a heading to exit the MVA. At the time traffic was starting to reduce after a moderate to heavy volume/complexity; and I was working out a sequence between Aircraft X and another aircraft (Aircraft Y). I believe controller judgement was the main contributing factor. I had recently changed the sequence and was planning to place Aircraft Y (a late center freq change) in front of Aircraft X. Also; after a moderate to heavy volume/complexity workload; I was thinking about the sequence and not the MVA until it was to late. Keeping Aircraft X at 3;000 ft.; would have kept this issue from occurring.
Air Traffic Controller reported assigning a correction vector heading after mistakenly assigning a previous vector which resulting in the aircraft flying below MVA.
