A Search for Radio Transients at 0.33 GHz in the GC

We report on a search for transient and variable radio sources in the Galactic center using a number of 327 MHz VLA observations made during the 1990's, and a series of monthly VLA observations made during Spring and Summer 2002. A typical yield of compact sources in a given epoch is roughly 20...

Summary:We report on a search for transient and variable radio sources in the Galactic center using a number of 327 MHz VLA observations made during the 1990's, and a series of monthly VLA observations made during Spring and Summer 2002. A typical yield of compact sources in a given epoch is roughly 200. We have detected one new bright radio transient, GCRT J1746–2757, located only 1.1 degrees north of the Galactic center. We discuss our on‐going transient monitoring program and the implications of this work for constraining the Galactic center population of transients.
