We report the first detection of microwave emission from coronal X-ray jets using simultaneously obtained imaging data at 17 GHz (Nobeyama Radioheliograph data) and in X-rays (Yohkoh/SXT data). We present detailed results for one jet on the disk and another at the limb. The 17 GHz emission in the disk event originates from the base (a loop or a system of loops) of the jet, and for the limb jet the microwave emission comes from the base as well as from a part of the X-ray jet. We believe that the collimated jet is optically thin at 17 GHz in most cases. We have investigated more than two dozen jet events and found 17 GHz emission in at least 70% of the cases. The 17 GHz emission is unpolarized. We interpret the microwave emission as thermal, related to the heating of the plasma responsible for the X-ray jet.
