摘要：

We present the first images of the Galactic plane (GP; \b\ < 5 degrees, -15 degrees < l < 255 degrees) at 8.35 and 14.35 GHz. These observations used the National Radio Astronomy Observatory-NASA Green Bank Earth Station to survey the sky simultaneously at these frequencies. These are the first results from the GP survey observations, a program to monitor the sky at 8.35 and 14.35 GHz. The GP survey series is intended to detect short-lived radio sources. We present four independent observations of the Galactic plane, combined to provide a set of reference images of the Galactic plane. The first survey, GPA, covers 0.82 sr (6.5%) of the sky. A source list is presented for all sources brighter than 0.9 Jy at 8.35 GHz and also for all sources brighter than 2.5 Jy at 14.35 GHz. The FITS format images, residual images, source lists, and archive data are available over the Internet. Later papers will present the results of the variable source search.
