Abstract: 
We suggest a new moduli functor of quasibundles on a smooth projective surface, which is a stack theoretic counterpart of the Uhlenbeck compactification, and briefly outline its relation with other compactifications constructed by other authors (Balaji, Timofeeva, Schmitt and a few others).
