Abstract

Simultaneous observations of SS433 at IR and visible wavelengths are reported. Three pronounced features are established: (1) an enormous apparent excess of IR over optical flux; (2) an almost flat spectrum for wavelengths greater than 1.2 microns; and (3) a variation of IR and optical flux together on a time scale of several days. The IR excess is attributed to a region of gas that radiates by free-free and free-bound emission processes with a total emission measure of the order of 10 to the 61st per cu cm.
