    Abstract

    We present results of two 1.4 GHz radio surveys of a +32° < δ < +42° area with four interferometers in the Nasu Radio-Transient Search Project. The observable area was 7.0% of the whole sky. The surveys were carried out between 2004 and 2005. All observed interferometric data were transformed to color images to construct color atlases of the 1.4 GHz sky. From these atlases, 144 radio sources were detected by comparison with the 1.4 GHz NRAO VLA Sky Survey Catalog, excluding the Cygnus region. The observed data will be used in a transient search alert system.
