These observations used the NRAO/NASA Green Bank Earth Station to survey the sky simultaneously at these frequencies.
These are the first results from the Galactic Plane (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. We compare the relative brightness of Cassiopeia A and Cygnus A and find the rate of decrease of Cassiopeia A is slower than previously reported.
The first survey, GPA, covers 0.82 sr (6.5%) of the sky. A source list is presented for all sources brighter than 0.9Jy at 8.35GHz and also for all sources brighter than 2.5 Jy at 14.35 GHz.
