We investigate the flicker of compact extragalactic sources on day-like time scales. Daily observations were made at 1410 MHz of 25 flat and 14 steep spectrum extragalactic radio sources during two observing sessions. The maximum time baseline for the 1410 MHz data is 58 days. We also observed these same sources at 820 MHz for 24 days overlapping the second 1410 MHz session. Ten of the flat spectrum sources were observed two years earlier at 1410 and 2380 MHz. At 1410 MHz the flat spectrum sources show larger intensity variations than do the steep spectrum sources. At 820 MHz measurement noise dominates the source variations, thus our observations yield an upper limit to the flicker amplitude at this frequency. The flicker amplitude appears to be weakly dependent upon observing wavelength, possibly increasing with increasing wavelength. No dependence of the intensity or time scale of flicker on galactic coordinates is apparent in this data set, but the number of flat spectrum sources observed may be too small to show any such effects. We present evidence that flicker is approximately stable in its characteristics over time scales at least as large as 2 yr.
