CI Aql in quiescence. The plot is of V-band magnitudes (with B-band magnitudes converted with B − V = 1.03 mag) taken from the Harvard plates, Schmidt sky surveys, Robocam, McDonald Observatory, and Cerro Tololo. Eclipses are excluded except for the two old Harvard plates, while the tails of the 1941 and 2000 eruptions should be ignored. What we are left with is a flat light curve during quiescence.
