(Condon+ 1982) J/AJ/87/1429 : Active Extragalactic Objects II (Condon+ 1982) Radio sources Three selected fields were observed with the Very Large Array (VLA) at 1411MHz as part of an ongoing project to compile complete samples of active extragalactic objects. The radio-source list for the field "A" centered on alpha=08h54m, delta=+17d30' is presented. 67 maps cover the area 3x3deg so that every point lies within at least one primary half-power beamwidth. The median map noise is 0.5mJy and the 6{sigma} completeness level is less than 6mJy over half the field. The synthesized point-source response is an elliptical Gaussian approximately 20x17" between half-intensity points. The areal density of sources with flux densities in the range 5<S<150mJy was determined. Optical identifications based on position coincidences with 90 objects brighter than B=~21.5 in the A and B survey fields are reported.
