We present a progress report on a survey of 16 Extra-solar planets around nearby stars. This survey used the Robert C Byrd Green Bank Telescope (GBT) for dual circularly polarized observations at 285 to 335 MHz. Using the GBT spectrometer, we produced high time and frequency resolution observations, searching for flaring events. To date, only upper limits can be placed on the flaring emission from these planets. Since cyclotron maser emission from Jupiter is episodic, long observations may be required to detect Extra-solar planets. Detection of Faint Radio Sources by Spectral Variation is Difficult!
