All magnetized planets in our solar system emit intense cyclotron maser radiation. Like Jupiter, the recently discovered extra-solar planets are probably magnetized. If in addition, there is a source of energetic (keV) electrons in their magnetospheres, it is likely that extra-solar planets are also cyclotron-maser emitters.
We present Green Bank 100m Radio Telescope observations at 330 MHz of 20 Extra-solar planets around nearby stars. Using the GBT spectrometer, we produced high time and frequency resolution observations, searching for flaring events. The calibration, radio interference and sensitivity limits are presented. Since cyclotron maser emission from Jupiter is episodic, long observations may be required to detect Extra-solar planets.
