On 17may12 project a2130 (galfacts) received
interference from the galileo satellite galileo-pfm (they saw it
on more than one night)
The plots show the galileo satellite passes over
arecibo for 7may12 - 31may12 (.ps) (.pdf):
The dynamic
spectra using stokes I showed the satellite as it went overhead
