O'Dell, S. L. ; Puschell, J. J. ; Stein, W. A. ; Warner, J. W. Abstract Tile characteristics of the changes in the shapes of the spectral-flux distributions of variable extragalactic sources have been observed over the wavelength range 0.36 i m to 3.5 ILm. Pronounced activity has been observed in the sources AO 0235+164, 3C 120, PKS 0735+178, OJ 287 (0851+202), and B2 1308+326. The slope of the spectral-flux distribution has been observed to change significantly in some cases during transitions in observed flux. Tilese changes are interpreted in terms of injection and energy loss of high-energy electrons radiating synchrotron radiation.
