Minor Planet Center shows a list of Asteroids (Figure 1) in need of observations. A few days ago, I saw the list and there was this asteroid 1984 QY1 which observation was “desirable”. It was not that dim at magnitude 16 so i had to observe it.

With unguided 60 seconds of sub exposures, i recorded it at 16.4 magnitude (Figure 2). Figure 3 shows the stacked image where the asteroid is right where it is supposed to be.
