Abstract
We raise the question of whether velocities of left and right circular ly-polarized photons might be different (for reasons other than the we ll-known Faraday effect). Such a difference could manifest itself eith er in the time profiles of pulsed or bursting astronomical sources or in the rotation of the direction of polarization of linearly polarized radiation from them. The existing observations of pulsars, gamma ray bursters, and quasar jets are used to set limits to the difference in speed, \c(L) - c(R)\/(c) over bar between 10(-17) and 10(-32).
